Detailed Description
While various embodiments are set forth below in detail, the present invention is not intended to be limited to all of the possible embodiments, and other embodiments not set forth herein may be utilized. Moreover, the dimensional ratios in the drawings are not to scale with actual products. Accordingly, the description and drawings are only for the purpose of illustrating embodiments and are not to be construed as limiting the scope of the invention. In addition, some elements are omitted from the drawings in the embodiments to clearly show the technical features of the present invention. The following description refers to the same or similar elements or steps with the same or similar reference numerals.
In this specification, terms such as "front direction", "left and right directions", or "bottom direction" of an element do not necessarily represent directions opposite to the element, but are used to describe a relative positional relationship with the element in space.
Fig. 1 is a schematic diagram illustrating a relative position relationship of some elements of a head-up display device 100 or 100' according to an embodiment of the invention. The head-up display device 100 or 100' may be a device installed under the dashboard of a vehicle (e.g., a vehicle), and may include an image generating unit 30, a first reflective plate 40, and a second reflective plate 11. The image generating unit 30 is used for generating an image displayed on the windshield, and the light L generating the image can be reflected by the first reflecting plate 40 and the second reflecting plate 11 in sequence, so as to project the image onto the windshield. In addition, the inclination angle of the second reflection plate 11 is generally configured to be adjustable, thereby adjusting the sharpness and the image position of the image projected onto the windshield.
In order to adjust the tilt angle of the second reflection plate 11, a tilt angle adjustment mechanism may be provided in the head-up display device 100 or 100'. In the present invention, by disposing the tilt angle adjusting mechanism in the remaining space S inside the head-up display device 100 or 100 ', the space of the head-up display device 100 or 100 ' can be effectively utilized without searching for an additional space for disposing the tilt angle adjusting mechanism, thereby reducing the volume of the head-up display device 100 or 100 '. Here, the existing remaining space S may be a space which does not affect the traveling path of the light L and has no element disposed therein, and its orientation is specifically a position in the front side direction of the second reflection plate 11, as indicated in fig. 1.
Fig. 2 is a perspective view of the head-up display device 100 according to an embodiment of the invention. The head-up display device 100 includes a tilt angle adjusting mechanism 10 and a base 20. The reclining angle adjusting mechanism 10 is provided on the base 20. In fig. 2, a part of the side wall of the base 20 is cut away to clearly show the appearance of the reclining angle adjusting mechanism 10.
The tilt angle adjusting mechanism 10 includes a reflection plate assembly 1, a transmission assembly 2 and a driving unit 3. The base 20 includes a first sidewall 201, a second sidewall 202, and a third sidewall 203. The second sidewall 202 and the third sidewall 203 are connected to the first sidewall 201. The base 20 further includes a bottom 204 connected to the first sidewall 201, the second sidewall 202 and the third sidewall 203, and the transmission assembly 2 and the driving unit 3 are disposed on the bottom 204. The driving unit 3 is, for example, a motor, and drives the transmission assembly 2. The transmission assembly 2 is connected between the reflection plate assembly 1 and the driving unit 3, and is used for transmitting the kinetic energy of the driving unit 3 to the reflection plate assembly 1, so as to drive the reflection plate assembly 1 to move.
The reflection plate assembly 1 includes a reflection plate 11, and the reflection plate 11 functions as described with reference to fig. 1. As shown in fig. 2, the driving unit 3 is disposed in the front direction of the reflection plate 11. The position of the front side direction of the reflection plate 11 can be described as: a position of an X-axis index value smaller than that of the reflection plate 11 on the X-axis within the inner space of the base 20. Here, the driving unit 3 is disposed at a position within the existing remaining space S shown in fig. 1. For example, please refer to fig. 3, which is a top view of the head-up display device 100 of fig. 2. The reflection plate 11 may be disposed adjacent to the first sidewall 201 of the base 20, and the driving unit 3 is disposed away from the first sidewall 201 of the base 20. With this configuration, the volume of the head-up display device 100 can be minimized.
As shown in fig. 2, the driving assembly 2 may include a driving rod 21 and a connecting member 22. The transmission rod 21 extends horizontally towards the reflection plate package 1. For example, the transmission rod 21 extends horizontally with the bottom surface 204 of the base 20 toward the reflective panel assembly 1. The connecting member 22 is disposed on the transmission rod 21, and the transmission assembly 2 is connected to the reflection plate assembly 1 through the connecting member 21. Therefore, when the driving unit 3 drives the transmission assembly 2, the reflection plate assembly 1 can be driven to move, and the inclination angle of the reflection plate 11 can be adjusted.
In one embodiment, the reflection plate assembly 1 may include a rotation shaft 12, and the rotation shaft 12 may be disposed between the second sidewall 202 and the third sidewall 203 of the base 20. When the driving unit 3 drives the transmission assembly 2, the reflection plate 11 rotates around the rotation shaft 12 to adjust the inclination angle of the reflection plate 11.
As shown in fig. 3, the parallel line of the rotating shaft 12 may form an included angle θ with the driving rod 21, and the included angle θ may be smaller than 90 degrees. In some embodiments, the included angle θ may be equal to, less than, or greater than 90 degrees, depending on the predetermined shape of the base 20 of the head-up display device 100. That is, by extending the transmission rod 21 horizontally toward the reflection plate assembly 1, the driving unit 3 can be disposed at any position in the front side direction of the reflection plate 11.
Fig. 4 is an exploded perspective view of the tilt angle adjusting mechanism 10 according to an embodiment of the invention. The connecting member 22 may have a guide groove 221, and the reflection plate assembly 1 may include a guide post 13. In one embodiment, the guide posts 13 can be disposed on one side 11s (shown in FIG. 1) of the reflective plate 11. Here, the guide post 13 is slidably disposed in the guide groove 221. Of course, the present invention is not limited to this configuration. For example, in another embodiment, the connector 22 may be a guide post and the reflective plate assembly 1 may have a similar guide slot.
Fig. 5A is a schematic operation diagram (i) illustrating a partial structure of the tilt angle adjusting mechanism 10 shown in fig. 4 from a perspective view. Referring to fig. 4 and 5A, when the driving unit 3 drives the transmission assembly 2, the transmission rod 21 can move linearly. Specifically, in one embodiment, the transmission assembly 2 may include a screw 24, a nut 25, and a guide 26. The screw 24 extends parallel to the drive rod 21 and the guide 26. The nut 25 is threaded on the screw 24 and is connected to the guide 26. Drive rod 21 may be connected to nut 25 and may be interlocked with nut 25. Specifically, driving rod 21 may include a positioning member 211, and positioning member 211 is fixed to nut 25, so that driving rod 21 is coupled with nut 25, and relative movement between driving rod 21 and nut 25 is prevented.
The driving unit 3 can drive the screw 24 to rotate around the X axis. When the driving unit 3 drives the transmission assembly 2, the screw 24 rotates to make the nut 25 move linearly along the X-axis on the guide 26, thereby driving the transmission rod 21 to move linearly along the X-axis.
In addition, in an embodiment, the transmission assembly 2 may further include a gear set 23, and the gear set 23 may be connected between the driving unit 3 and the screw 24. That is, the kinetic energy of the driving unit 3 is transmitted to the reflection plate assembly 1 through the power transmission paths of the gear set 23, the screw 24, the nut 25, the transmission rod 21 and the connection member 22 in sequence. Here, the designer may decide an appropriate reduction ratio to adjust the design of the gear set 23.
As shown in FIG. 5A, the drive link 21 can include opposing first and second ends 21e1 and 21e2 in the X-axis direction. The positioning member 211 of the transmission rod 21 can be disposed on the first end 21e1, and the connecting member 22 can be disposed on the second end 21e2, but the invention is not limited thereto.
As shown in fig. 4 and 5A, the guide groove 221 of the connecting member 22 may be a straight groove. When the driving unit 3 drives the driving assembly 2, the guide post 13 of the reflection plate assembly 1 may slide in the guide groove 221. With this structure, the transmission rod 21, the connecting member 22 and the guide post 13 form a link mechanism, so that the reflection plate 11 can rotate around the rotation shaft 12 to adjust the inclination angle of the reflection plate 11. Of course, the invention is not limited to this design.
Fig. 5B is a schematic operation diagram (one) illustrating the tilt angle adjusting mechanism 10 of fig. 4 from a side view. Fig. 6A is a schematic operation diagram (two) illustrating a partial structure of the tilt angle adjusting mechanism 10 shown in fig. 4 from a perspective view. Fig. 6B is a schematic operation diagram (two) illustrating the tilt angle adjusting mechanism 10 of fig. 4 from a side view.
Referring to fig. 5A and 5B, fig. 5B is a schematic diagram illustrating the reflector 11 at the first position. At this time, the guide post 13 is positioned at the first end 221e1 of the guide groove 221. When the drive unit 3 drives the transmission assembly 2, the position of the guide post 13 in the guide groove 221 will change.
Referring to fig. 6A and 6B, fig. 6B is a schematic diagram illustrating the reflection plate 11 at the second position. When the driving unit 3 drives the transmission assembly 2, the transmission rod 21 moves linearly in the positive direction of the X-axis to drive the guide post 13 to slide toward the second end 221e2 of the guide groove 221, so that the reflection plate 11 can rotate around the rotation shaft 12 to change the inclination angle of the reflection plate 11.
In addition, in these embodiments, the arrangement of the driving rod 21, the guiding groove 221 and the guiding post 13 can be further applied to the reflective plates 11 with different size designs. In detail, the above-mentioned purpose of applying to the reflection plates 11 with different size designs can be achieved by adjusting the included angle between the guide groove 221 and the transmission rod 21.
Fig. 7A to 7D are schematic operation diagrams of the reflection plates 111 and 112 with different sizes according to the embodiment of the invention. The size of the reflection plate 111 of fig. 7A and 7B is larger than that of the reflection plate 112 of fig. 7C and 7D. In fig. 7A and 7B, the angle between the guide groove 221 and the driving lever 21 can be adjusted to α for application to the reflection plate 111 of a larger size. In fig. 7C and 7D, the angle between the guide groove 221 and the driving lever 21 can be adjusted to be β for application to the reflection plate 112 of a smaller size. The included angle α is smaller than the included angle β, so that the reflective plate 111 and the reflective plate 112 can be adjusted within the same range of tilt angles. That is, in the embodiment of the present invention, the included angle between the guide groove 221 and the driving rod 21 is adjustable, thereby being applicable to reflective plates with different sizes.
Fig. 8 is a perspective view of a head-up display device 100' according to another embodiment of the invention. Fig. 9 is a top view of the heads-up display device 100' of fig. 8. The head-up display device 100 'includes a tilt angle adjusting mechanism 10' and a base 20. The tilt angle adjusting mechanism 10' is disposed on the base 20.
The tilt angle adjusting mechanism 10' includes a reflection plate assembly 1, a transmission assembly 2, and a driving unit 3. In the present embodiment, the driving unit 3 is also disposed at a position within the existing remaining space S shown in fig. 1. Therefore, the volume of the head-up display device 100' can be minimized.
In the present embodiment, the relative positional relationship of some elements of the head-up display device 100' is similar to the head-up display device 100 shown in the embodiment of fig. 2, and the description of the same or similar elements is not repeated here.
Fig. 10 is a perspective view of a reclining angle adjusting mechanism 10' according to another embodiment of the present invention. Referring to fig. 8, 9 and 10, the driving assembly 2 includes a driving rod 21 'and a connecting member 22'. One difference from the head-up display device 100 shown in the embodiment of fig. 2 is that: in the present embodiment, the driving rod 21' can make a rotational movement when the driving unit 3 drives the driving assembly 2. In an embodiment, the transmission assembly 2 may further comprise a worm-drive set 27, and the worm-drive set 27 may be connected between the driving unit 3 and the transmission rod 21'. That is, the kinetic energy of the driving unit 3 is transmitted to the reflective plate assembly 1 through the power transmission paths of the worm gear set 27, the transmission rod 21 'and the connecting member 22' in sequence. Here, the designer can increase or decrease the transmission mechanism design between the driving unit 3 and the transmission rod 21' according to the determined reduction ratio.
The connecting member 22 'may be a worm, and the reflection plate assembly 1 may include a worm gear portion 13'. In one embodiment, the worm 13' may be disposed on one side 11s of the reflective plate 11. The worm gear portion 13' may be curved, and the length of the curved shape determines the range of the adjustable inclination angle of the reflection plate 11. Here, the worm gear 13 'can engage with the worm (i.e. the connecting piece 22').
In one embodiment, the connecting member 22 ' can be connected to the driving rod 21 ' and can be coupled to the driving rod 21 '. I.e. no relative movement between the connecting piece 22 'and the transmission rod 21' is possible. Therefore, when the driving unit 3 drives the transmission assembly 2 to rotate the transmission rod 21 'about the X-axis, the connecting member 22' rotates. In this way, the connecting member 22 'can drive the worm gear 13' engaged therewith, so that the reflective plate 11 can rotate around the rotating shaft 12 as an axis to adjust the inclination angle of the reflective plate 11. Of course, the invention is not limited to this design.
Fig. 11 is a schematic side view illustrating an operation of the tilt angle adjusting mechanism 10' of fig. 10. Fig. 12 is a schematic operation diagram (two) of the tilt angle adjusting mechanism 10' of fig. 10 from a side view.
Referring to fig. 11, a schematic diagram of the reflector 11 at the first position is shown. When the driving unit 3 drives the transmission assembly 2, the transmission rod 21 'and the connecting member 22' rotate around the axis X to drive the worm gear 13 'engaged with the connecting member 22'. This allows the reflecting plate 11 to rotate about the rotating shaft 12, thereby changing the inclination angle of the reflecting plate 11. As shown in fig. 12, the reflection plate 11 is shifted from the first position of fig. 11 to the second position.
In addition, in these embodiments, the above-mentioned configurations of the transmission rod 21 ', the connecting member 22 ' and the worm gear 13 ' can be applied to the reflective plate 11 with different sizes.
Please refer to fig. 13, which is a partially enlarged view of the tilt angle adjusting mechanism 10' of fig. 10. By adjusting the intercept P and the helix angle gamma of the worm (i.e., the connecting member 22'), the above-mentioned objective of applying to the reflective plates 11 of different sizes can be achieved. In detail, if the pitch circle of the worm is the same, the worm with a longer intercept P and a larger helix angle γ can be used to drive the reflector 11 with a larger size; in contrast, a worm screw having a shorter intercept P and a smaller helix angle γ can be used to drive the reflecting plate 11 of a smaller size.
The tilt angle adjusting mechanisms 10 and 10 'and the head-up display devices 100 and 100' of the above embodiments are disposed at a position in the existing remaining space S shown in fig. 1, for example, at a position in a front direction of the reflective plate, or at a position away from a first sidewall of the chassis, where the reflective plate is disposed at a position adjacent to the first sidewall. Therefore, the space of the head-up display device 100, 100 'can be effectively utilized, and no additional space is required to be searched for installing the tilt angle adjusting mechanism, thereby minimizing the volume of the head-up display device 100, 100'. Furthermore, the tilt angle adjusting mechanisms 10 and 10 'and the head-up display devices 100 and 100' provided in the above embodiments are more applicable to reflective plates with different sizes.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
