[0056] To provide a further understanding of the purpose, structure, features and functions of the present invention, detailed descriptions are provided below with reference to embodiments.

[0057] Please refer to Figures 1A-3B , Figure 1A A schematic diagram (first state) of a projector 10 according to an embodiment of the present invention is shown. Figure 1B Draw Figure 1A A cross-sectional view of the projector 10 along direction 1B-1B'. Figure 1C Draw Figure 1A An internal schematic diagram of the projector 10 (excluding the casing 11), Figure 2A Draw Figure 1A A schematic diagram of the projector 10 in the second state. Figure 2B Draw Figure 2A An internal schematic diagram of the projector 10 (excluding the casing 11), Figure 3A Draw Figure 1A A schematic diagram of the projector 10 in the third state, while Figure 3B Draw Figure 3AA schematic diagram of the internal structure of the projector 10 (casing 11 omitted). The X, Y, and Z directions in the diagram are perpendicular to each other.

[0058] like Figures 1A-1C As shown, the projector 10 is configured in a mobile vehicle. The projector 10 includes an optical engine module 200 and an adjustment module 100. The adjustment module 100 is connected to the optical engine module 200 and includes a knob 105. When the knob 105 is in a first state, the optical engine module 200 is allowed to rotate about a first axis AX1. When the knob 105 is in a second state, the optical engine module 200 is allowed to rotate about a second axis AX2. The directions of the first axis AX1 and the second axis AX2 are different. In practice, when the knob 105 is in the first state, rotating the knob 105 rotates the optical engine module 200 about the first axis AX1. When the knob 105 is in the second state, rotating the knob 105 rotates the optical engine module 200 about the second axis AX2. Thus, by operating the same knob in different states, the optical engine module can be driven to rotate about different axes.

[0059] like Figures 1A-1C As shown, the projector 10 includes a housing 11, an adjustment module 100, an optical engine module 200, a V-shaped reflector module 300, a carrier plate 400, a fixing component 450, a fixing shaft 470, a pivot component 480, a connector 490, and a drive module 500.

[0060] like Figures 1A-1C As shown, the projector 10 can be configured in a mobile vehicle, such as in the dashboard of a mobile vehicle. For example, the housing 11 includes a first fixing part 11A and a second fixing part 11B, and the housing 11 is fixed to the mobile vehicle by the first fixing part 11A and the second fixing part 11B. The projector 10 can project at least one image onto the dashboard. The mobile vehicle is, for example, a mobile vehicle including at least one wheel, such as a car, bus, truck, etc. However, the mobile vehicle can also be configured in other types of vehicles, such as a boat, airplane, etc. The V-shaped reflector module 300 includes a first reflector 310, a second reflector 320 and a carrier 330, wherein the carrier 330 is fixed to the optical engine module 200, and the first reflector 310 and the second reflector 320 are configured on the carrier 330 in a V-shape. The image projected by the optical-mechanical module 200 is incident on the first reflector 310 and the second reflector 320, and is reflected by the first reflector 310 and the second reflector 320 to two areas of the instrument panel respectively.

[0061] like Figures 1A-1CAs shown, the V-shaped mirror module 300 is configured relative to the optomechanical module 200. An adjustment module 100 is connected to the optomechanical module 200 and includes a knob 105. When the knob 110 is in a first state, the optomechanical module 200 is allowed to rotate about a first axis AX1. When the knob 105 is in a second state, the optomechanical module 200 is allowed to rotate about a second axis AX2. Thus, by operating the same knob 110 in different states, the optomechanical module 200 can be driven to rotate about different axes.

[0062] like Figure 1A As shown, the central axis of knob 105 is defined as the third axis AX3, which is approximately parallel to the Z direction. The aforementioned first axis AX1 is approximately parallel to the X direction, while the second axis AX2 is approximately parallel to the Y direction.

[0063] like Figure 1A As shown, the housing 11 has an outer surface 11s and a groove 11r, wherein the groove 11r is recessed relative to the outer surface 11s. Figure 1A As shown, when the knob 105 is in the first state, the knob 105 protrudes relative to the outer surface 11s of the housing 11. Figure 1A and 2A As shown, during the process of knob 105 changing from the first state to the second state, knob 105 moves along the third axis AX3 towards the housing 11, but knob 105 still protrudes relative to the outer surface 11s of the housing 11. Figure 2A and 3A As shown, during the transition from the second state to the third state, the knob 105 moves along the third axis AX3 toward the housing 11. When the knob 105 is in the third state, it is approximately flush with the outer surface 11s of the housing 11, or it is recessed relative to the outer surface 11s of the housing 11. The groove 11r and the knob 105 have a groove length L1 and a knob length L2 respectively in the same direction (e.g., parallel to the X direction), with the groove length L1 being greater than the knob length L2. Thus, although the knob 105 does not protrude relative to the outer surface 11s of the housing 11, the user's fingers or tools can enter the groove 11r to move the knob 105 away from the housing 11 along the third axis AX3. In one embodiment, the operation of the knob 105 may not be electrically driven but manually operated by the user.

Figure 4B Draw Figure 4A A cross-sectional view of the adjustment module 100 along direction 4B-4B'.

Figure 6B Draw Figure 6A A cross-sectional view of the adjustment module 100 along direction 6B-6B', and Figure 6C Draw Figure 6A A cross-sectional view of the adjustment module 100 along direction 6C-6C'.

[0065] like Figures 4A-4F The adjustment module 100 also includes a first housing 110, a second housing 115, a first fitting 120, a third fitting 125, a clutch 130, a fixing member 137, an adapter 140, a sliding member 145, a sliding plate 150, a latch 155, an elastic member 160, a first screw 165, and a spring 170.

[0066] like Figure 4D and 4E As shown, the first outer shell 110 includes a plate 111, a first limiting portion 112, and a second limiting portion 113. The first limiting portion 112 and the second limiting portion 113 are connected to the plate 111. The first limiting portion 112 has a first recess 112r, and the second limiting portion 113 has a second recess 113r. The first recess 112r can accommodate a portion of the first fitting member 120 to limit the first fitting member 120, for example, restricting the displacement freedom of the first fitting member 120 and the base plate 110 in the Z direction. The second recess 113r can accommodate a portion of the third fitting member 125 to limit the third fitting member 125, for example, restricting the displacement freedom of the third fitting member 125 and the base plate 110 in the Z direction.

[0067] like Figure 4D and 4EAs shown, the second outer casing 115 includes a third limiting portion 1151 and a fourth limiting portion 1152. The third limiting portion 1151 has a third recess 1151r, and the fourth limiting portion 1152 has a fourth recess 1152r. The third recess 1151r can accommodate a portion of the first fitting member 120 to limit the first fitting member 120, for example, restricting the displacement freedom of the first fitting member 120 and the base plate 110 in the Z direction. The fourth recess 1152r can accommodate a portion of the third fitting member 125 to limit the third fitting member 125, for example, restricting the displacement freedom of the third fitting member 125 and the base plate 110 in the Z direction.

[0068] like Figure 4D and 4E As shown, the second outer shell 115 and the first outer shell 110 can be fixed to each other. For example, the first outer shell 110 further includes at least one first fastening portion 114, and the second outer shell 115 further includes at least one second fastening portion 1153. The first fastening portion 114 and the second fastening portion 1153 can be fastened to each other to fix the relative position of the first outer shell 110 and the second outer shell 115. One of the first fastening portion 114 and the second fastening portion 1153 is, for example, a hook, and the other of the first fastening portion 114 and the second fastening portion 1153 is, for example, a slot.

[0069] like Figure 4D and 4E As shown, the second housing 115 has a first receiving groove 115r1, at least one second receiving groove 115r2, and at least one through hole 115r3. The first receiving groove 115r1 can accommodate at least a portion of the clutch 130, the slider 145, the slide plate 150, the latch 155, and the elastic member 160. The second receiving groove 115r2 can accommodate the spring piece 170. The through hole 115r3 connects the first receiving groove 115r1 and the second receiving groove 115r2, allowing the end 171 of the spring piece 170 to enter the first receiving groove 115r1 through the through hole 115r3 to contact the slider 145 located in the first receiving groove 115r1.

[0070] like Figure 4D and 4E As shown, the first fitting member 120 is rotatably disposed on the first housing 110 and the second housing 115. The first fitting member 120 and the third fitting member 125 are kept in a fitted state, so that when the clutch 130 is engaged with the first fitting member 120, the power of the clutch 130 can be transmitted to the third fitting member 125 through the first fitting member 120. The first fitting member 120 has a plurality of first fitting portions 121, and the third fitting member 125 has a plurality of third fitting portions 1251, and the plurality of first fitting portions 121 of the first fitting member 120 and the plurality of third fitting portions 1251 of the third fitting member 125 are kept in engagement. In one embodiment, the first fitting portions 121 and the third fitting portions 1251 may have teeth that can engage with each other.

[0071] like Figure 4D and 4E As shown, the second engaging member 131 of the clutch 130 can selectively engage with the first engaging member 120. For example, when the knob 105 is in the first state, the second engaging member 131 engages with the first engaging member 120. Figure 5A As shown, when knob 105 is in the second state, the second fitting 131 disengages from the first fitting 120. Figure 6A As shown, when knob 105 is in the third state, the second fitting 131 also disengages from the first fitting 120. Figures 6A-6B As shown, when knob 105 is in the third state, knob 105 engages with the second housing 1151 to lock knob 105. For example, as Figure 6A As shown, the second housing 115 has a plurality of housing engagement portions 1155, and the knob 105 has a plurality of knob engagement portions 1051. When the knob 105 is in the third state, the plurality of housing engagement portions 1155 engage with the plurality of knob engagement portions 1051, thereby restricting the relative rotational freedom of the knob 105 and the second housing 115. In one embodiment, the housing engagement portions 1155 and the knob engagement portions 1051 are, for example, mating teeth. In summary, the third state is the locked state of the knob 105.

[0072] like Figure 4A and 4E As shown, the second engaging member 131 of the clutch 130 has a plurality of second engaging portions 1311, while the first engaging member 120 also has a plurality of fourth engaging portions 122. The plurality of fourth engaging portions 122 of the second engaging member 131 can selectively engage with the plurality of second engaging portions 1311 of the clutch 130. Figure 4A As shown, when the knob 105 is in the first state, the plurality of fourth engagement portions 122 of the second engagement member 131 engage with the plurality of second engagement portions 1311 of the clutch 130. Thus, when the clutch 130 rotates about the third shaft AX3, the clutch 130 can drive the first engagement member 120 to rotate, thereby driving the third engagement member 125 to rotate synchronously. Figure 5A As shown, when the knob 105 is in the second state, the plurality of fourth engagement portions 122 of the second engagement member 131 disengage from the plurality of second engagement portions 1311 of the clutch 130. Thus, when the clutch 130 rotates around the third shaft AX3, the clutch 130 cannot drive the first engagement member 120 and the third engagement member 125 to rotate. Figure 6AAs shown, when the knob 105 is in the third state, the second engagement member 131 disengages from the plurality of fourth engagement portions 122 of the clutch 130, just as the plurality of second engagement portions 1311 of the clutch 130 disengage. In one embodiment, the fourth engagement portions 122 and the second engagement portions 1311 are, for example, mating gear teeth. Furthermore, the second engagement member 131 of the clutch 130 also has a plurality of fifth engagement portions 1312, which are, for example, gear teeth, and can selectively engage with the drive module 500, as described later.

[0073] In this embodiment, the aforementioned first fitting member 120, second fitting member 131 and third fitting member 125 are, for example, gear structures, but the embodiments of the present invention are not limited thereto.

[0074] Please refer to Figures 7A-7B Its illustration Figure 6A Exploded views of clutch 130 from different perspectives.

[0075] like Figures 7A-7B As shown, the clutch 130 is connected to the knob 105, slidably configured relative to the first housing 110, and includes the aforementioned second fitting member 131. The clutch 130 includes a clutch shaft 132 and a fixing member 133. The clutch 130 can be considered as a one-piece structure, that is, there is no relative movement between the aforementioned second fitting member 131, clutch shaft 132, and fixing member 133. The clutch shaft 132 includes an engagement end 1321, a first shaft body 1322, a limiting portion 1323, and a second shaft body 1324. The first shaft body 1322 connects the engagement end 1321 and the limiting portion 1323, while the limiting portion 1323 connects the first shaft body 1322 and the second shaft body 1324.

[0076] like Figures 7A-7B As shown, the second fitting 131 has a through hole 131a, and the engagement end 1321 of the clutch shaft 132 engages with the through hole 131a of the second fitting 131. In this embodiment, the through hole 131a and the engagement end 1321 can be designed in shapes other than circular, such as D-shaped. The engagement end 1321 and the through hole 131a each have a major diameter and a minor diameter in two different directions, so that after the through hole 131a engages with the engagement end 1321, the clutch shaft 132 and the second fitting 131 will not rotate relative to each other. Thus, when the clutch shaft 132 rotates around the third axis AX3, it can drive the second fitting 131 to rotate synchronously around the third axis AX3. In addition, the fixing member 133 can press against the second fitting 131 and fix it in the fixing hole 1321a of the engagement end 1321 to fix the relative position of the clutch shaft 132 and the second fitting 131. In an embodiment, the fastener 133 has, for example, a male thread, while the fixing hole 1321a has, for example, a mating female thread hole.

[0077] like Figure 4C and 7AAs shown in ~7B, the clutch shaft 132 and the first fitting 120 are slidable relative to each other. For example, the first shaft body 1322 of the clutch shaft 132 and the through hole 120a of the first fitting 120 (through hole 120a is shown in...) Figure 4C Loosening engagement. Thus, when clutch 130 is relative to first engagement member 120 along third axis AX3 (third axis AX3 is shown in...) Figure 4C Sliding. In this way, the movement of clutch 130 along the third axis AX3 is not restricted by the first fitting 120 (since the first fitting 120 is constrained between the first housing 110 and the second housing 115, it cannot move along the third axis AX3).

[0078] like Figure 4C and 7A As shown in ~7B, the limiting portion 1323 of the clutch shaft 132 can be coupled to the slide plate 150, allowing the limiting portion 1323 and the slide plate 150 to move synchronously. For example, the limiting portion 1323 has a groove 1323r, and the limiting portion 153 of the slide plate 150 can be located within the groove 1323r. Thus, when the clutch 130 slides along the third shaft AX3, it can drive the slide plate 150 to move synchronously in the Z direction. The groove 1323r of the limiting portion 1323 has opposing first limiting side 1323r1 and second limiting side 1323r2, and the limiting portion 153 of the slide plate 150 can be located between the first limiting side 1323r1 and the second limiting side 1323r2, so that the limiting portion 153 of the slide plate 150 is constrained between the first limiting side 1323r1 and the second limiting side 1323r2. Furthermore, the limiting portion 153 of the slide plate 150 and the groove 1323r of the limiting portion 1323 of the clutch shaft 132 are, for example, transition fit or loose fit, allowing the clutch 130 and the slide plate 150 to rotate relative to each other around the third axis AX3, that is, the slide plate 150 does not affect the rotation of the clutch 130. In one embodiment, the groove 1323r is, for example, a full circumference (i.e., 360-degree) groove, so that the clutch 130 and the slide plate 150 can rotate relative to each other by 360 degrees.

[0079] like Figure 4C and 7AAs shown in ~7B, the second shaft 1324 of the clutch shaft 132 of the clutch 130 is connected to the adapter 140 in a non-rotatable manner. For example, the through hole 140a1 of the second shaft 1324 and the adapter 140 is designed in a shape other than a circle, such as a D-shape. The second shaft 1324 and the through hole 140a1 each have a major diameter and a minor diameter in two different directions, so that when the second shaft 1324 and the through hole 140a1 are engaged, the clutch shaft 132 and the adapter 140 will not rotate relative to each other. Thus, when the adapter 140 rotates about the third shaft AX3, it can drive the clutch 130 to rotate synchronously about the third shaft AX3. Alternatively, the second shaft 1324 of the clutch shaft 132 and the adapter 140 can be slidably connected. For example, the second shaft 1324 and the through hole 140a1 of the adapter 140 are a transition fit or a loose fit, allowing the clutch 130 and the adapter 140 to slide relative to each other. Figure 4C As shown, when the knob 105 is in the first state, there is a space between the end of the second shaft 1324 and the side wall of the through hole 140a1, which provides a sliding stroke S1 for the clutch 130 and the adapter 140 to slide relative to each other. Thus, as... Figure 5C and 6C As shown, when knob 105 is in the second state ( Figure 5C Switch to the third state ( Figure 6C When the clutch 130 can no longer move in the -Z direction (details to follow), the adapter 140 can still continue to move in the -Z direction relative to the clutch 130.

[0080] like Figure 4C As shown, the fixing member 137 can pass through the through hole 105a of the knob 105 and be fixed in the fixing hole 140a2 of the adapter 140 to fix the relative position between the knob 105 and the adapter 140. Thus, when the knob 105 rotates about the third axis AX3, it can drive the adapter 140 and the clutch 130 to rotate synchronously about the third axis AX3. In an embodiment, the fixing member 137, for example, has a male thread, and the fixing hole 140a2, for example, has a female thread that mates with the male thread.

[0081] like Figure 4C , 4EAs shown in Figure 4F, the adapter 140 and the slider 145 are rotatably connected but not slidably connected. The adapter 140 includes a body 141, a first limiting part 142, a second limiting part 143, and a fixed end 144. The body 141 can pass through the through hole 145a1 of the slider 145. The second limiting part 143 connects the body 141 and the fixed end 144. The fixed end 144 has the aforementioned fixing hole 140a2. The first limiting part 142 is connected to the body 141, for example, to the end of the body 141. The first limiting part 142 and the second limiting part 143 respectively abut against opposite sides of the slider 145 to restrict the relative displacement freedom of the adapter 140 and the slider 145 along the third axis AX3. Thus, when the adapter 140 moves along the third axis AX3, the adapter 140 can drive the slider 145 to move synchronously in the Z direction. In this embodiment, the first limiting part 142 is, for example, a hook, which can prevent the adapter 140 from disengaging from the slider 145 in the +Z direction. The outer diameter D1 of the second limiting part 143 is larger than the inner diameter D2 of the through hole 145a1 of the body 141, thus preventing the adapter 140 from disengaging from the slider 145 in the -Z direction. Figure 4C As shown, the body 141 of the adapter 140 and the through hole 145a1 of the slider 145 are, for example, transition fit or loose fit. For example, the outer diameter D3 of the body 141 is smaller than the inner diameter D2 of the through hole 145a1, so that the adapter 140 and the slider 145 can rotate relative to each other.

[0082] Please refer to Figures 8A-10 , Figure 8A Draw Figure 4D Assembly diagram (first state) of clutch 130, first housing 110, sliding member 145, slide plate 150 and spring plate 170. Figure 8B Draw Figure 8A Assembly diagram of slider 145 and spring 170. Figure 8C Draw Figure 8B Exploded view of slider 145 and spring piece 170. Figure 9 Draw Figure 8A A schematic diagram showing knob 105 in its second state, while Figure 10 Draw Figure 9 A schematic diagram of knob 105 in the third state.

[0083] like Figures 8A-8C As shown, the slider 145 has a first recess 145r1, a second recess 145r2, and a third recess 145r3. When the slider 145 moves along the Z direction, one of the first recess 145r1, the second recess 145r2, and the third recess 145r3 can engage with the spring piece 170. For example, as... Figure 8A As shown, when the knob 105 is in the first state, the end 171 of the spring piece 170 is located in the first recess 145r1. Figure 9As shown, when the knob 105 is in the second state, the end 171 of the spring piece 170 is located in the second recess 145r2. Figure 10 As shown, when the knob 105 is in the third state, the end 171 of the spring 170 is located in the third recess 145r3. Through the temporary engagement design of the multiple recesses and the spring 170, a segmented switching feel can be generated when the slider 145 moves in the Z direction.

[0084] like Figure 8A As shown, the first recess 145r1 has a sidewall 145r1s that overlaps with the end portion 171 in the Z direction, and the sidewall 145r1s is closer to the knob 105 in the +Z direction than the end portion 171. The end portion 171 can stop the sidewall 145r1s of the slider 145 from moving in the -Z direction. Unless an external force is applied that overcomes the elasticity of the spring plate 170, the spring plate 170 can stop the slider 145 from moving in the -Z direction. Furthermore, the clutch 130 cannot move in the +Z direction due to the stop of the first engaging member 120. Figure 8A and 9 As shown, during the transition of knob 105 from the first state to the second state, slider 145 overcomes the elastic force of spring 170 (e.g., by applying an external force) and moves relative to spring 170 in the -Z direction. Similarly, as Figure 9 and 10 As shown, during the process of switching the knob 105 from the second state to the third state, the slider 145 overcomes the elastic force of the spring 170 (e.g., by applying an external force) and moves relative to the spring 170 in the -Z direction.

[0085] Depend on Figure 8A and Figure 9 It can be seen that during the transition from the first state to the second state, the knob 105 moves along the -Z direction to drive the adapter 140, the slider 145, and the slide plate 150 to move synchronously along the -Z direction. In the second state, as... Figure 9 As shown, the slide plate 150 is stopped by the limiting portion (e.g., the first limiting portion 112 and / or the second limiting portion 113) of the first housing 110 and cannot move in the -Z direction. Figure 9 and Figure 10 It can be seen that during the transition from the second state to the third state, the knob 105 moves along the -Z direction to drive the adapter 140 and the slider 145 to move synchronously along the -Z direction, but the slide plate 150 does not move synchronously and remains in the position of the second state (e.g., Figure 9 (as shown in the image).

[0086] like Figure 4D and 4EAs shown, the slide plate 150 and the first housing 110 are slidable relative to each other. For example, the plate body 111 of the first housing 110 has at least one groove 110a1, and the slide plate 150 includes a plate body 151, at least one slider 152, the aforementioned limiting portion 153, and at least one stop 154, wherein the plate body 151 has opposing first surfaces 151s1 and second surfaces 151s2, and the slider 152 is disposed on the first surface 151s1 of the plate body 151 and protrudes relative to the first surface 151s1. When the first housing 110 and the slide plate 150 are combined, the slider 152 is slidably engaged with the groove 110a1. In an embodiment, the groove 110a1 extends, for example, along the Z direction, so that the slide plate 150 and the first housing 110 are slidable relative to each other along the Z direction. The stop 154 ​​is connected to the side of the plate body 151.

[0087] like Figure 9 As shown, when the knob 105 is in the second state, the stop 154 ​​can abut against the limiting portion of the first housing 110 (e.g., the first limiting portion 112 and / or the second limiting portion 113), thus, when the knob 105 moves from the second state ( Figure 9 Switch to the third state ( Figure 10 During the process, the slide plate 150 cannot move in the -Z direction due to the stop of the limiting part of the first outer shell 110.

[0088] During the process of switching knob 105 from the first state to the second state, slider 145 and slide plate 150 are connected in a non-sliding manner. During the process of switching knob 105 from the second state to the third state, slider 145 and slide plate 150 are connected in a sliding manner, as further illustrated below.

[0089] like Figure 4B , 5B As shown in Figure 6B, the slide plate 150 has a recess 150a, which can penetrate the plate body 151 (plate body 151 is shown in Figure 6B). Figure 4D A latch 155 is disposed on a slider 145. The latch 155 and slider 145 are non-slidably connected in the Z direction but slidably connected in the X direction. For example, the latch 155 has a limiting end 1551. The limiting end 1551 of the latch 155 can be located within a recess 150a of the slide plate 150, allowing the slider 145 and slide plate 150 to move synchronously; for example, the limiting end 1551 drives the slide plate 150 to move in the Z direction. Thus, as... Figure 4B and 5B As shown, during the process of switching knob 105 from the first state to the second state, slider 145 and slide plate 150 move synchronously along the -Z direction. Figure 5B and 6BAs shown, during the process of switching the knob 105 from the second state to the third state, the slide plate 150 remains stationary relative to the first housing 110. After the slider 145 continues to move relative to the slide plate 150 in the -Z direction, the limiting end 1551 of the latch 155 is forced to move in the +X direction and disengage from the recess 150a. Furthermore, as... Figure 5C and 6C As shown, since the adapter 140 and the clutch 110 are slidably connected in the -Z direction, the knob 105 can be switched from the second state ( Figure 5C Switch to the third state ( Figure 6C During the process, knob 105 can continue to move in the -Z direction.

[0090] like Figure 5C and 6C As shown, during the transition of knob 105 from the second state to the third state, because the slide plate 150 is stopped by the first housing 110, the clutch 130 also cannot move in the -Z direction (there is no relative sliding between the clutch 130 and the slide plate 150 in the Z direction). Thus, the second engagement member 131 of the clutch 130 can be held in the position it was in in the second state (e.g., ...). Figure 5C (As shown in the diagram), the second engagement member 131 at this position engages with the drive module 500. Specifically, since the clutch 130 (or slide plate 150) and the knob 105 can slide relative to each other in the -Z direction in the second state, during the transition of the knob 105 from the second state to the third state, the second engagement member 131 of the clutch 130 can be maintained in the position of the second state, while the knob 105 can continue to move in the -Z direction to the position of the third state (if the clutch 130 and the knob 105 cannot slide relative to each other, the second engagement member 131 is in contact with the drive module 500, and the knob 105 cannot continue to move in the -Z direction to the position of the third state). In the second state, the second engagement member 131 of the clutch 130 engages with the drive module 500, allowing the clutch 130 to drive the optomechanical module 200 to rotate around the second axis AX2, as described later.

[0091] like Figure 4C and 11A As shown in ~11B, Figures 11A-11B Draw Figure 4D Exploded views of the slider 145, elastic member 160, and latch 155 from different perspectives. The slider 145, elastic member 160, and latch 155 can form a sliding module. The slider 145 also has a receiving hole 145a2 and a limiting hole 145a3, wherein the receiving hole 145a2 and the limiting hole 145a3 communicate. The latch 155 is slidably disposed in the receiving hole 145a2 along the X direction. The elastic member 160 is disposed within the receiving hole 145a2 and is located between the latch 155 and the slider 145. Thus, as... Figure 6BAs shown, when the latch 155 moves away from the recess 150a, the elastic element 160 deforms (e.g., compresses) to store elastic potential energy. When the elastic element 160 is released, it releases the elastic potential energy, causing the limiting end 1551 to enter the recess 150a, as... Figure 5B As shown.

[0092] like Figures 11A-11B As shown, the latch 155 also includes at least one limiting portion 1552, which is slidably located in the limiting hole 145a3 of the slider 145. The limiting portion 1552 abuts against the sidewall 145a31 of the limiting hole 145a3 to prevent the latch 155 from disengaging from the slider 145 in the -X direction. Specifically, although the elastic member 160 applies a preload to the latch 155 in the -X direction, the latch 155 will not disengage from the slider 145 in the -X direction because the limiting portion 1552 abuts against the sidewall 145a31 of the limiting hole 145a3.

[0093] like Figures 11A-11B As shown, the latch 155 also includes an end portion 1553, and the slider 145 further has a receiving hole 145a4. The end portion 1553 overlaps with the receiving hole 145a4 in the X direction. Thus, as Figure 5B and 6B As shown, when knob 105 is in the second state ( Figure 5B ) and the third state ( Figure 6B When the latch 155 is in the position of the receiving hole 145a4, the end 1553 and the receiving hole 145a4 can be located in the receiving hole 145a4 to avoid interference between the latch 155 and the slider 145.

[0094] like Figure 4D As shown, the first screw 165 and the third fitting 125 are connected to each other. For example, the first screw 165 and the third fitting 125 can be fixedly connected to each other. Thus, the third fitting 125 and the first screw 165 can rotate synchronously. In one embodiment, the first screw 165 and the third fitting 125 are, for example, an integrally formed structure. In terms of material, the first screw 165 and the third fitting 125 can be made of plastic. In terms of manufacturing process, the first screw 165 and the third fitting 125 can, for example, be integrally formed using injection molding technology. Furthermore, the first screw 165 can be connected to a carrier 400 (carrier 400 is shown in...). Figure 1C This drives the carrier disk 400 to rotate about the first axis AX1, as will be explained later.

[0095] like Figures 8A-8CAs shown, the spring piece 170 has an end 171, which enters the first receiving groove 115r1 through the through hole 115r3 of the second housing 115 to engage with one of the first recess 145r1, the second recess 145r2, and the third recess 145r3 of the slider 145. The spring piece 170 has a limiting groove 170r, and the second housing 115 includes at least one limiting post 1154, which is disposed on the groove sidewall of the second receiving groove 115r2 of the second housing 115. When the spring piece 170 is located in the second receiving groove 115r2, the limiting post 1154 engages with the limiting groove 170r, thereby restricting the relative displacement freedom of the spring piece 170 and the second housing 115. In this embodiment, the limiting groove 170r can extend along the X direction. Thus, when the limiting post 1154 engages with the limiting groove 170r, the relative displacement freedom of the spring piece 170 and the second outer shell 115 along the Y direction can be restrained. The limiting post 1154 and the limiting groove 170r form a fixed point. When the spring piece 170 is subjected to an external force (e.g., the slider 145 presses the spring piece 170), due to the support of the fixed point, the spring piece 170 can deform relative to the fixed point (e.g., deform in the Y direction), causing the end 171 of the spring piece 170 to retract inward toward the second receiving groove 115r2. Furthermore, when the end 171 of the spring piece 170 is located in the recess of the slider 145 (e.g., one of the first recess 145r1, the second recess 145r2, and the third recess 145r3), the spring piece 170 still has a pre-deformation amount. Therefore, the spring piece 170 can apply an elastic abutment force to the side wall of the second receiving groove 115r2, making it difficult for the spring piece 170 to disengage from the second receiving groove 115r2.

[0096] Please refer to Figures 1B-1C and 12A~12B, Figure 12A and 12B Draw Figure 1C Exploded views of the V-shaped reflector module 300, carrier plate 400, at least one fixing member 450, fixing shaft 470 and drive module 500 from two different perspectives.

[0097] like Figures 1B-1CAs shown in Figures 12A-12B, the carrier disk 400 is connected to the optomechanical module 200 and has a first screw hole 400a1, with a first screw 165 screwed into the first screw hole 400a1. In this embodiment, the first screw 165 and the first screw hole 400a1 remain screwed together regardless of whether it is in the first, second, or third state. The first screw hole 400a1 extends along the Z direction, and the distance between the first screw hole 400a1 and the first axis AX1 along the Y direction is H1. When the first screw 165 rotates around the + / -Z direction, it can drive the carrier disk 400 and the optomechanical module 200 to rotate synchronously (since the fixing member 450 connects the carrier disk 400 and the optomechanical module 200, the carrier disk 400 and the optomechanical module 200 can rotate synchronously) around the first axis AX1. In one embodiment, when the first screw 165 rotates about the -Z direction, the optomechanical module 200 can rotate about the first axis AX1 in a first direction (e.g., one of the +X and -X directions); when the first screw 165 rotates about the +Z direction, the optomechanical module 200 can rotate about the first axis AX1 in a second direction (e.g., the other of the +X and -X directions). When the knob 105 is in the first state, for each revolution of the knob 105, the optomechanical module 200 can rotate about the first axis AX1 by a first predetermined angle, wherein the first predetermined angle depends on the thread design (e.g., lead) and distance H1 of the first screw 165, and is not limited in this embodiment. In one embodiment, the first predetermined angle is, for example, 0.5 degrees.

[0098] like Figures 1B-1C As shown in Figures 12A-12B, the fixed shaft 470 can be fixed to the carrier 400, for example, the fixed shaft 470 is screwed onto the carrier 400. The first shaft AX1 in this document coincides with the central axis of the fixed shaft 470, or the central axis of the fixed shaft 470 defines the first shaft AX1. Furthermore, as... Figure 1B As shown, the fixed shaft 470 passes through the through hole 11a of the housing 11, and there is a gap between the through hole 11a and the fixed shaft 470. Thus, when the fixed shaft 470 rotates around the first axis AX1 (for example, the carrier disk 400 drives the fixed shaft 470 to rotate around the first axis AX1), the housing 11 and the fixed shaft 470 do not interfere with each other.

[0099] like Figures 1B-1C As shown in Figures 12A and 12B, the carrier disk 400 and the optomechanical module 200 are connected in a non-rotatable manner around the first axis AX1. For example, the optomechanical module 200 has at least one fixing hole 200a1, while the carrier disk 400 has at least one through hole 400a2, wherein the fixing member 450 connects the fixing hole 200a1 and the through hole 400a2 along the Y direction. Thus, when the carrier disk 400 rotates around the first axis AX1 (which is parallel to the X direction), the optomechanical module 200 and the carrier disk 400 rotate synchronously around the first axis AX1.

[0100] The second axis AX2 of this document coincides with the central axis of the fixing hole 200a1, or the central axis of the fixing hole 200a1 defines the second axis AX2. The fixing member 450 is screwed into the fixing hole 200a1. In one embodiment, the fixing member 450 has, for example, a male thread, while the fixing hole 200a1 has, for example, a female thread that mates with the male thread.

[0101] like Figure 1B and 12A As shown in ~12B, the carrier disk 400 has at least one through hole 400a2, through which the fixing member 450 can pass. The fixing member 450 and the through hole 400a2 are, for example, transition fit or loose fit, so that the carrier disk 400 and the fixing member 450 can rotate relative to each other about the second axis AX2, thereby allowing the optomechanical module 200 (which is fixed to the fixing member 450) and the carrier disk 400 to rotate relative to each other about the second axis AX2. Thus, when the optomechanical module 200 rotates about the second axis AX2, the carrier disk 400 does not move.

[0102] like Figure 12B As shown, the pivot 480 is connected to the drive module 500 and the optomechanical module 200. Thus, when the drive module 500 drives the pivot 480 to push the optomechanical module 200, the optomechanical module 200 rotates about the second axis AX2. Since the optomechanical module 200 and the carrier disk 400 can rotate relative to each other about the second axis AX2, the carrier disk 400 does not rotate when the drive module 500 drives the pivot 480 to push the optomechanical module 200 to rotate about the second axis AX2.

[0103] like Figure 12A and 12B As shown, the optomechanical module 200 has a through hole 200a2, the pivot member 480 has a through hole 480a1, and the connector 490 connects the through hole 200a2 of the optomechanical module 200 and the through hole 480a1 of the pivot member 480. Thus, the pivot member 480 and the optomechanical module 200 can rotate relative to the connector 490. Furthermore, the through holes 200a2, 480a1, and the connector 490 are, for example, loosely fitted to provide rotational freedom for the pivot member 480, the connector 490, and the optomechanical module 200, so that when the drive module 500 drives the optomechanical module 200 to rotate, the rotational resistance of the optomechanical module 200 is small or minimal (if the rotational resistance of the optomechanical module 200 is large, it may push the drive module 500 backwards).

[0104] like Figure 12A and 12BAs shown, the drive module 500 includes a second screw 501, and a pivot 480 connected to the optomechanical module 200 and having a second screw hole 480a2. The second screw 501 is screwed into the second screw hole 480a2. In this embodiment, the second screw 501 and the second screw hole 480a2 remain engaged regardless of whether it is in the first state, the second state, or the third state. The second screw hole 480a2 extends along the X direction, and the distance between the second screw hole 480a2 and the first axis AX1 along the Z direction is H2. Thus, when the second screw 501 rotates about the X direction, the pivot 480 can move along the X direction, thereby driving the optomechanical module 200 to rotate about the second axis AX2. In one embodiment, when the second screw 501 rotates about the -X direction, the optomechanical module 200 can rotate about the second axis AX2 in a first direction (e.g., one of the +Y and -Y directions); when the second screw 501 rotates about the +X direction, the optomechanical module 200 can rotate about the second axis AX2 in a second direction (e.g., the other of the +Y and -Y directions). When the knob 105 is in the second state, for each revolution of the knob 105, the optomechanical module 200 can rotate about the second axis AX2 by a second predetermined angle, wherein the second predetermined angle depends on the thread design (e.g., lead) of the second screw 501, the design of the distance H2, and the reduction ratio of the gear set driving the diaphragm assembly, and is not limited in this embodiment. In one embodiment, the second predetermined angle is, for example, 0.5 degrees.

[0105] like Figure 12A and 12B As shown, the drive module 500 includes, for example, a gear set (e.g., a first gear 510, a second gear 513, a third gear 515, a fourth gear 520, and at least one fifth gear 525) and an adapter plate 530. The first gear 510 is connected to the second gear 513 and can rotate synchronously. The second gear 513 meshes with the third gear 515. The first gear 510, the second gear 513, and the third gear 515 are, for example, bevel gears. Furthermore, the first gear 510 and the second gear 513 can be pivotally connected to the adapter plate 530, which can be fixed to the housing 11 (not shown). Figure 12A and 12B For example, it is fixed to the housing 11 by screws. The third gear 515 and the fourth gear 520 are connected to each other and can rotate synchronously. The third gear 515 and the fourth gear 520 are sleeved on the fixed shaft 470 and can rotate relative to the fixed shaft 470, for example, the third gear 515 and the fourth gear 520 are loosely fitted to the fixed shaft 470. The fourth gear 520 meshes with one of the fifth gears 525, while the other fifth gears 525 remain engaged. In this way, when the first gear 510 rotates, it can drive the second gear 513, the third gear 515, the fourth gear 520 and the plurality of fifth gears 525 to rotate synchronously. In addition, the plurality of fifth gears 525 can be pivotally connected to the carrier 400.

[0106] like Figure 1C , 12A As shown in 12B, when knob 105 is in the second state (as shown in Figure 12B) Figure 1C As shown), the second engaging member 131 of the aforementioned clutch 130 can engage with the first gear 510. When the second engaging member 131 rotates about the third shaft AX3, it can drive the first gear 510, the second gear 513, the third gear 515, the fourth gear 520, and multiple fifth gears 525 to rotate synchronously. The second screw 501 is connected to the gear located at the end of a power transmission path among the multiple gears of the drive module 500, for example, the fifth gear 525'. The second screw 501 is fixed to the fifth gear 525' to rotate synchronously. When the knob 105 is in the second state (e.g. Figure 1C As shown, the knob 105 can rotate around the third axis X3 to drive the second screw 501 to rotate around the X direction, thereby driving the optical engine module 200 to rotate around the second axis AX2. Since the optical engine module 200 and the carrier disk 400 can rotate relative to each other around the second axis AX2, the carrier disk 400 does not need to rotate with the optical engine module 200 when it rotates around the second axis AX2, so that the relative relationship between the carrier disk 400 and the drive module 500 does not easily change.

[0107] Please refer to Figures 13A-13C , Figure 13A A schematic diagram of a projector 20 according to another embodiment of the present invention is shown (the housing 11 is not shown). Figure 13B Draw Figure 13A An exploded view of the projector 20, and Figure 13C Draw Figure 13A A cross-sectional view of the projector 20 along direction 13B-13B'.

[0108] like Figures 13A-13C As shown, the projector 20 includes a housing 11 (not shown), an adjustment module 100, an optical engine module 200A, a V-shaped reflector module 300A, a carrier plate 400, a fixing member 450, a fixing shaft 470, a pivot member 480 (not shown), a connector 490 (not shown), a drive module 500, an adapter 600, a third screw 650, and at least one fixing member 670. The projector 20 includes the same or similar technical features as the aforementioned projector 10, with at least one difference in that the V-shaped reflector module 300A and the optical engine module 200A are relatively displaceable, making the position of the V-shaped reflector module 300A adjustable relative to the optical engine module 200A.

[0109] like Figures 13A-13CAs shown, the V-shaped reflector module 300A includes a first reflector 310, a second reflector 320, and a carrier 330. The carrier 330 is movable relative to the optomechanical module 200A, and the first reflector 310 and the second reflector 320 are disposed on the carrier 330 in a V-shape. The image projected by the optomechanical module 200A is incident on the first reflector 310 and the second reflector 320, and is reflected by the first reflector 310 and the second reflector 320 to two areas of the instrument panel, respectively.

[0110] like Figures 13A-13C As shown, the optical engine module 200A includes a lens 210. An adapter 600 is fixed to the optical engine module 200A. A V-shaped mirror module 300A is slidably connected to the optical engine module 200A. A third screw 650 is rotatably connected to the V-shaped mirror module 300A. The V-shaped mirror module 300A has a third screw hole 300a1, which engages with the third screw 650. In this embodiment, the third screw hole 300a1 is, for example, disposed on a carrier 330. The third screw 650 can drive the V-shaped mirror module 300A to move along a fourth axis AX4 to adjust the relative position of the mirrors (e.g., the first mirror 310 and the second mirror 320) and the optical engine module 200A along the fourth axis AX4. In this embodiment, the fourth axis AX4 is parallel to the Z direction; however, in another embodiment, depending on the extension direction of the central axis of the third screw hole 300a1, the fourth axis AX4 may be parallel to the X direction. In this embodiment, the third screw hole 300a1 extends, for example, along the Z direction; in another embodiment, the third screw hole 300a1 may extend along the X direction.

[0111] like Figures 13A-13C As shown, the adapter 600 has a through hole 600a1. The aforementioned third screw 650 passes through the through hole 600a1 and is screwed into the third screw hole 300a1 of the V-shaped reflector module 300A. In an embodiment, the through hole 600a1 and the third screw 650 are rotatable relative to each other. For example, the through hole 600a1 and the third screw 650 are loosely fitted, allowing the third screw 650 to rotate relative to the adapter 600.

[0112] like Figures 13A-13C As shown, the V-shaped reflector module 300 also has at least one elongated hole 300a2, which can be disposed on the carrier 330. In this embodiment, the long axis of the elongated hole 300a2 extends parallel to the extension direction of the fourth axis AX4 to provide the V-shaped reflector module 300 with a travel distance along the fourth axis AX4.

[0113] like Figures 13A-13CAs shown, the optomechanical module 200A has at least one through hole 200a2, and the adapter 600 also has at least one fixing hole 600a2. The fixing member 670 passes through the elongated hole 300a2 and the through hole 200a2 and is fixed to the fixing hole 600a2. The fixing member 670 and the through hole 200a2 are, for example, loosely fitted, and the fixing member 670 and the elongated hole 300a2 are, for example, loosely fitted. In one embodiment, the fixing member 670 has, for example, a male thread, and the fixing hole 600a2 has, for example, a female thread that mates with the male thread. Furthermore, the outer diameter of the fixing member 670 is approximately equal to the inner diameter of the fixing hole 600a2, so that the fixing member 670 and the adapter 600 have no relative movement along the XY plane. Furthermore, the adapter 600 is fixed to the carrier disk 400. Thus, there is no relative movement between the carrier disk 400, the adapter 600, and the optomechanical module 200A.

[0114] In summary, this invention provides a projector comprising an adjustment module and an optical engine module. The adjustment module includes a knob, which can be in different states to operate different movement modes of the optical engine module. When the knob is in a first state, rotating the knob causes the optical engine module to rotate around a first axis. When the knob is in a second state, rotating the knob causes the optical engine module to rotate around a second axis. Thus, by operating the same knob in different states, the optical engine module can be driven to rotate around different axes. In this embodiment, as long as the projector has an adjustment module and an optical engine module, the adjustment function (i.e., the optical engine module rotates around different axes) can be achieved. Furthermore, as long as the adjustment function can be achieved, this invention does not limit the mechanism and / or structure of the projector's components, and the mechanism and / or structure of the projector's components are not limited by the foregoing embodiments. In another embodiment, when the knob is in a third state, the knob cannot be rotated (locked state), which prevents the knob from being easily rotated due to accidental touch.

[0115] Although the invention has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the invention and should not be construed as limiting the invention. The scale in the schematic drawings does not represent the actual proportions of the components, in order to clearly describe the required parts.

[0116] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
