Description

抬頭顯示器結構Heads-up display structure

本發明關於抬頭顯示器領域，特別關於抬頭顯示器的結構改良，以簡化抬頭顯示器的結構。The present invention relates to the field of head-up display, and more particularly to a structural improvement of a head-up display to simplify the structure of the head-up display.

抬頭顯示器(Head-Up Display, HUD)原為航空飛行器的飛行輔助儀器，但是現今抬頭顯示器也已應用於汽車等領域，方便使用者無須大幅度移動視線到其他位置，減少低頭查看手機或儀表板的機會，將影像透過光學反射的原理反射到使用者前方的擋風玻璃上，讓影像直接呈現在使用者的視野前方，提供使用者更方便且更安全的駕駛體驗。Head-Up Display (HUD) was originally a flight aid for aircraft, but now it has also been applied to automobiles and other fields, so that users do not need to move their eyes to other places, reducing the chance of looking down at mobile phones or instrument panels. The image is reflected to the windshield in front of the user through the principle of optical reflection, so that the image is directly presented in front of the user's field of vision, providing users with a more convenient and safer driving experience.

抬頭顯示器中可以有預先設置的影像投影系統，或是設置手機架供使用者將手機放置於手機架，藉由抬頭顯示器中內建的曲面鏡將影像投影系統或手機所呈現的影像透過光學反射的方式，讓影像呈現在使用者的眼前。The head-up display may have a pre-set image projection system, or a mobile phone holder may be provided for the user to place the mobile phone on the mobile phone holder, and the image presented by the image projection system or the mobile phone may be optically reflected by the built-in curved mirror in the head-up display so that the image is presented in front of the user.

不過由於抬頭顯示器需要因應擺放於車輛或航空飛行器的位置調整曲面鏡角度，藉以使影像可以呈現在所想要的位置，因此一般抬頭顯示器結構中會設置有傳動機構及旋轉軸夾持器(holder)，而曲面鏡會設置有旋轉軸，旋轉軸夾持器用於夾持曲面鏡的旋轉軸，並且一般會設置有金屬彈片防止曲面鏡的震動，而傳動機構則與曲面鏡連接，藉以使曲面鏡以旋轉軸為軸心進行旋轉，但是這樣的結構設計仍有問題有待解決。However, since the head-up display needs to adjust the angle of the curved mirror according to the position of the vehicle or aircraft so that the image can be presented at the desired position, a transmission mechanism and a rotation axis holder are generally provided in the head-up display structure, and the curved mirror is provided with a rotation axis. The rotation axis holder is used to clamp the rotation axis of the curved mirror, and a metal spring is generally provided to prevent the vibration of the curved mirror. The transmission mechanism is connected to the curved mirror so that the curved mirror rotates around the rotation axis. However, such a structural design still has problems to be solved.

首先現行抬頭顯示器的發展趨勢，為朝向微小化及提高視野範圍(Field of View, FOV)的方向發展，而現行常採用調整方式為縮窄抬頭顯示器下半部的殼體，並增加曲面鏡的面積大小，但是在先前技術中，為了對曲面鏡的旋轉軸進行限位，就必須要設置旋轉軸夾持器，而要設置旋轉軸夾持器就代表必須在抬頭顯示器中預留設置旋轉軸夾持器的空間，因此一般會在抬頭顯示器的側壁旁需預留9毫米的距離，藉以留置空間以設置旋轉軸夾持器，但這也壓縮到抬頭顯示器內的空間，導致難以進一步增加曲面鏡的面積，即難以進一步增加視野範圍，影響抬頭顯示器小型化和提高視野範圍的發展。First of all, the current development trend of head-up displays is to develop towards miniaturization and increase the field of view (FOV). The current adjustment method is to narrow the shell of the lower half of the head-up display and increase the size of the curved mirror. However, in the previous technology, in order to limit the rotation axis of the curved mirror, a rotation axis clamp must be set. To set a rotation axis clamp means that the rotation axis must be reserved in the head-up display. Therefore, a distance of 9 mm is generally reserved next to the side wall of the head-up display to leave space for setting the rotating shaft clamp, but this also compresses the space inside the head-up display, making it difficult to further increase the area of the curved mirror, that is, it is difficult to further increase the field of view, which affects the development of miniaturization of the head-up display and improvement of the field of view.

此外，旋轉軸夾持器會需要在特定角度進行組裝，而要在抬頭顯示器內部有限的空間中組裝旋轉軸夾持器並不容易，並且由於還需要另外生產旋轉軸夾持器以及將旋轉軸夾持器固定在抬頭顯示器的殼體的零件，導致生產抬頭顯示器所需要的時間成本及金錢成本增加。In addition, the swivel axis clamp needs to be assembled at a specific angle, and it is not easy to assemble the swivel axis clamp in the limited space inside the head-up display. In addition, since the swivel axis clamp and the parts for fixing the swivel axis clamp to the head-up display housing need to be produced separately, the time cost and financial cost required to produce the head-up display increase.

本發明的一目的在於解決先前技術中需要另外設置旋轉軸夾持器，限制抬頭顯示器朝向微小化及提高視野範圍的發展，並且增加生產抬頭顯示器所需要的時間成本及金錢成本的問題。One purpose of the present invention is to solve the problem that the prior art requires the installation of a rotary axis clamp, which limits the development of the head-up display towards miniaturization and improvement of the field of view, and increases the time cost and financial cost required for the production of the head-up display.

The present invention provides a head-up display structure, including an upper shell 1, a lower shell 2, a transmission mechanism 3 and a curved mirror 4. The upper shell 1 is used to be assembled with the lower shell 2 to form the shell structure of the head-up display, and the transmission mechanism 3 and the curved mirror 4 are arranged in the shell structure formed by the upper shell 1 and the lower shell 2. The lower shell 2 is provided with at least one rotating shaft connecting block 20, and each rotating shaft connecting block 20 is provided with a rotating shaft receiving groove 22. The curved mirror 4 includes a rotating shaft 40, and the rotating shaft 40 is arranged in the rotating shaft receiving groove 22. The transmission mechanism 3 is connected to the curved mirror 4, so that the curved mirror 4 rotates with the rotation axis 40 as the axis. In addition, the head-up display structure of the present invention includes a built-in image projection device (not shown in the figure) or a shelf (not shown in the figure). The shelf is used for users to place image projection devices such as mobile phones, so that users can play the images to be presented through the built-in image projection device or image projection devices such as mobile phones, and let the image be reflected by the reflection surface of the curved mirror 4 to the object in front of the user's field of vision. For example, when the user uses it in a car, the object is the windshield in front of the user, so the image can be reversed on the windshield, so that the user can directly view the image in front of the field of vision.

請參閱圖1、圖2、圖4、圖5、圖7及圖8，於本發明的一實施例中，上殼體1本身即為遮光結構，設置於下殼體2的上方，用於遮蔽雜散光，藉以避免雜散光影響而降低抬頭顯示器經由光學反射所呈現的影像的清晰度及對比度。Please refer to Figures 1, 2, 4, 5, 7 and 8. In one embodiment of the present invention, the upper shell 1 itself is a shading structure, which is arranged above the lower shell 2 to shield stray light, so as to avoid the influence of stray light and reduce the clarity and contrast of the image presented by the head-up display through optical reflection.

請參閱圖2、圖5及圖8，於本發明的一實施例中，曲面鏡4可為球面鏡、非球面鏡或自由曲面鏡(free-form mirror, FFM)，用於放大並反射所要投射的影像，於本發明較佳的實施例中，曲面鏡4為自由曲面鏡，除了放大並反射所要呈現的影像外，同時相較於球面鏡及非球面鏡在設計上具有更高的自由度，且可以設計為更小的尺寸進而減輕重量，此外還可以減少影像畸變，提供使用者更加良好的使用體驗。Please refer to Figures 2, 5 and 8. In one embodiment of the present invention, the curved mirror 4 can be a spherical mirror, an aspherical mirror or a free-form mirror (FFM), which is used to magnify and reflect the image to be projected. In a preferred embodiment of the present invention, the curved mirror 4 is a free-form mirror. In addition to magnifying and reflecting the image to be presented, it also has a higher degree of freedom in design compared to a spherical mirror and an aspherical mirror, and can be designed to be smaller in size to reduce weight. In addition, it can also reduce image distortion and provide users with a better user experience.

請參閱圖1、圖2及圖3，於本發明的一實施例中，傳動機構3與曲面鏡4的一側以連接桿連接，而曲面鏡4的旋轉軸40則設置於旋轉軸容置槽22中，而上殼體1進一步包括有遮光牆10及開口遮蓋塊12，遮光牆10及開口遮蓋塊12設置於上殼體1的內側，於本實施例中，遮光牆10及開口遮蓋塊12為一體成型的態樣，但實際實施時不限於此，遮光牆10和開口遮蓋塊12也可為獨立設置的態樣。遮光牆10用於減少雜散光的產生，因此於本實施例中，遮光牆10為波浪狀設計，藉以抑制光線散射的狀況，降低雜散光的產生，以提供更良好的影像顯示效果。開口遮蓋塊12用於與旋轉軸連接塊20連接，並遮蓋旋轉軸連接塊20上的旋轉軸容置槽22的開口，因此旋轉軸容置槽22夾設於開口遮蓋塊12與旋轉軸連接塊20之間。於本實施例中，上殼體1及下殼體2使用螺絲進行組裝，以形成外殼結構。基於前述結構說明，當傳動機構3使曲面鏡4進行轉動時，由於曲面鏡4的旋轉軸40設置於旋轉軸容置槽22中，並且旋轉軸容置槽22的開口受到上殼體1的開口遮蓋塊12遮擋，因此曲面鏡4在被傳動機構3轉動時，由於曲面鏡4的旋轉軸40受到限位，因此曲面鏡4會以旋轉軸40為軸心進行旋轉。對曲面鏡4的旋轉軸40進行限位的目的，在於防止旋轉軸40在轉動過程中，或者是使用者在駕駛車輛或航空飛行器等交通工具的過程中，因為出現旋轉速度過快或震動過大等狀況，而導致曲面鏡4的旋轉軸40由旋轉軸容置槽22的開口掉出而脫落，進而造成曲面鏡4無法正常放大並反射所要呈現的影像，甚至造成曲面鏡4因為碰撞而毀損。因此藉由上殼體1的開口遮蓋塊12遮擋旋轉軸容置槽22的開口，使旋轉軸40僅能在旋轉軸容置槽22中進行轉動，因此當傳動機構3轉動曲面鏡4時，曲面鏡4即會以旋轉軸40為軸心進行旋轉，藉以達到調節曲面鏡4角度的目的，同時也防止曲面鏡4的脫落。Please refer to Figures 1, 2 and 3. In one embodiment of the present invention, the transmission mechanism 3 is connected to one side of the curved mirror 4 by a connecting rod, and the rotating shaft 40 of the curved mirror 4 is arranged in the rotating shaft accommodating groove 22, and the upper shell 1 further includes a shading wall 10 and an opening covering block 12, and the shading wall 10 and the opening covering block 12 are arranged on the inner side of the upper shell 1. In this embodiment, the shading wall 10 and the opening covering block 12 are in an integrally formed state, but the actual implementation is not limited to this. The shading wall 10 and the opening covering block 12 can also be in an independently arranged state. The light shielding wall 10 is used to reduce the generation of stray light, so in this embodiment, the light shielding wall 10 is designed in a wavy shape to suppress the light scattering and reduce the generation of stray light to provide a better image display effect. The opening cover block 12 is used to connect with the rotating shaft connecting block 20 and cover the opening of the rotating shaft receiving groove 22 on the rotating shaft connecting block 20, so the rotating shaft receiving groove 22 is sandwiched between the opening cover block 12 and the rotating shaft connecting block 20. In this embodiment, the upper shell 1 and the lower shell 2 are assembled using screws to form an outer shell structure. Based on the above structural description, when the transmission mechanism 3 causes the curved mirror 4 to rotate, since the rotation axis 40 of the curved mirror 4 is arranged in the rotation axis accommodating groove 22, and the opening of the rotation axis accommodating groove 22 is blocked by the opening cover block 12 of the upper shell 1, when the curved mirror 4 is rotated by the transmission mechanism 3, since the rotation axis 40 of the curved mirror 4 is limited, the curved mirror 4 will rotate with the rotation axis 40 as the axis. The purpose of limiting the rotation axis 40 of the curved mirror 4 is to prevent the rotation axis 40 of the curved mirror 4 from falling out of the opening of the rotation axis receiving groove 22 due to excessive rotation speed or excessive vibration during the rotation process or when the user is driving a vehicle or aircraft. This will cause the curved mirror 4 to be unable to normally magnify and reflect the image to be presented, and even cause the curved mirror 4 to be damaged due to collision. Therefore, the opening of the rotating shaft accommodating groove 22 is blocked by the opening cover block 12 of the upper shell 1, so that the rotating shaft 40 can only rotate in the rotating shaft accommodating groove 22. Therefore, when the transmission mechanism 3 rotates the curved mirror 4, the curved mirror 4 will rotate around the rotating shaft 40 as the axis, thereby achieving the purpose of adjusting the angle of the curved mirror 4 and preventing the curved mirror 4 from falling off.

前述態樣僅為示範例，但實際實施時不限於此，傳動機構3也可為連接曲面鏡4的下緣或背側等位置，藉以使曲面鏡4進行旋轉，所述曲面鏡4的背側為指曲面鏡4上相對於曲面鏡4的反射面的一側。當傳動機構3為連接曲面鏡4的下緣或背側時，旋轉軸40可為拆分成兩段的形式，並分別設置於曲面鏡4的左右兩側，下殼體2的左右兩側則分別設置有旋轉軸連接塊20，左右兩側的旋轉軸連接塊20上也分別設置有旋轉軸容置槽22，藉以容置左右兩側的旋轉軸40，而上殼體1的左右兩側也分別設置有遮光牆10及開口遮蓋塊12，因此在組裝上殼體1及下殼體2後，開口遮蓋塊12會與對應的旋轉軸連接塊20連接，並使旋轉軸容置槽22夾設於開口遮蓋塊12與旋轉軸連接塊20之間，藉以達到對曲面鏡4左右兩側的旋轉軸40進行限位的目的，因此當傳動機構3在曲面鏡4的背側或下方推動曲面鏡4進行旋轉時，由於曲面鏡4的左右兩側的旋轉軸40皆夾設於旋轉軸容置槽22中，並且受到開口遮蓋塊12的限位，因此曲面鏡4會以旋轉軸40為軸心進行旋轉。前述僅為示範例，實際實施時不限於此，旋轉軸40不限於拆分為兩段的形式，也可為一條完整的軸桿，並且可為貼附於曲面鏡4的背側，或貫穿曲面鏡4的形式，本發明並不特別限制。The above-mentioned aspects are merely examples, but are not limited thereto in actual implementation. The transmission mechanism 3 may also be connected to the lower edge or back side of the curved mirror 4 to rotate the curved mirror 4. The back side of the curved mirror 4 refers to the side of the curved mirror 4 that is opposite to the reflective surface of the curved mirror 4. When the transmission mechanism 3 is connected to the lower edge or back side of the curved mirror 4, the rotating shaft 40 can be split into two sections and respectively arranged on the left and right sides of the curved mirror 4, and the left and right sides of the lower shell 2 are respectively provided with rotating shaft connecting blocks 20, and the rotating shaft connecting blocks 20 on the left and right sides are also respectively provided with rotating shaft accommodating grooves 22 to accommodate the rotating shafts 40 on the left and right sides, and the left and right sides of the upper shell 1 are also respectively provided with shading walls 10 and opening cover blocks 12, so that after the upper shell 1 and the lower shell 2 are assembled, the opening cover block 12 is 2 will be connected to the corresponding rotating shaft connecting block 20, and the rotating shaft accommodating groove 22 is sandwiched between the opening cover block 12 and the rotating shaft connecting block 20, so as to achieve the purpose of limiting the rotating shaft 40 on the left and right sides of the curved mirror 4. Therefore, when the transmission mechanism 3 pushes the curved mirror 4 to rotate at the back or bottom of the curved mirror 4, since the rotating shafts 40 on the left and right sides of the curved mirror 4 are both sandwiched in the rotating shaft accommodating groove 22 and are limited by the opening cover block 12, the curved mirror 4 will rotate with the rotating shaft 40 as the axis. The above is only an example, and the actual implementation is not limited to this. The rotating shaft 40 is not limited to being split into two sections, but can also be a complete shaft, and can be attached to the back side of the curved mirror 4, or pass through the curved mirror 4. The present invention is not particularly limited.

請參閱圖4、圖5及圖6，於本發明的另一實施例中，上殼體1沒有設置前述的遮光牆10，而是直接設置開口遮蓋塊12，在此態樣下，上殼體1與下殼體2組裝後，上殼體1仍可以藉由開口遮蓋塊12的底部與旋轉軸連接塊20的頂部連接，且旋轉軸容置槽22夾設於開口遮蓋塊12與旋轉軸連接塊20之間，因此藉由上殼體1和下殼體2組裝後，藉由上殼體1的開口遮蓋塊12遮蓋旋轉軸連接塊20的頂部的旋轉軸容置槽22的上方開口，藉以對旋轉軸40進行限位，防止旋轉軸40因為旋轉速度過快或駕駛期間發生震動的關係，而使旋轉軸40掉出旋轉軸容置槽22，因此當傳動機構3轉動曲面鏡4並連帶使旋轉軸40一同轉動時，可以使旋轉軸40在被轉動期間仍維持在處於旋轉軸容置槽22中的狀態，因此當傳動機構3轉動曲面鏡4時，曲面鏡4即會以旋轉軸40為軸心進行旋轉，藉以達到調節曲面鏡4角度的目的。Please refer to FIG. 4, FIG. 5 and FIG. 6. In another embodiment of the present invention, the upper shell 1 is not provided with the aforementioned light shielding wall 10, but is directly provided with an opening cover block 12. In this state, after the upper shell 1 and the lower shell 2 are assembled, the upper shell 1 can still be connected to the top of the rotating shaft connecting block 20 through the bottom of the opening cover block 12, and the rotating shaft receiving groove 22 is sandwiched between the opening cover block 12 and the rotating shaft connecting block 20. Therefore, after the upper shell 1 and the lower shell 2 are assembled, the rotating shaft connecting block 20 at the top of the rotating shaft connecting block 20 is covered by the opening cover block 12 of the upper shell 1. The upper opening of the shaft receiving groove 22 is used to limit the rotating shaft 40 to prevent the rotating shaft 40 from falling out of the rotating shaft receiving groove 22 due to excessive rotation speed or vibration during driving. Therefore, when the transmission mechanism 3 rotates the curved mirror 4 and causes the rotating shaft 40 to rotate together, the rotating shaft 40 can be maintained in the rotating shaft receiving groove 22 during the rotation. Therefore, when the transmission mechanism 3 rotates the curved mirror 4, the curved mirror 4 will rotate with the rotating shaft 40 as the axis, so as to achieve the purpose of adjusting the angle of the curved mirror 4.

請參閱圖7、圖8及圖9，於本發明的又一實施例中，上殼體1沒有設置前述的遮光牆10及前述的開口遮蓋塊12，而是在下殼體2的旋轉軸連接塊20的頂部設置遮擋體24，下殼體2的旋轉軸連接塊20的頂部設置有旋轉軸容置槽22，並且旋轉軸容置槽22的開口朝上，因此利用將遮擋體24設置旋轉軸連接塊20的頂部的旋轉軸容置槽22的開口上方，即利用遮擋體24取代前述的開口遮蓋塊12的作用，對曲面鏡4的旋轉軸40進行限位，達到如同前述防止旋轉軸40出現震動而掉出旋轉軸容置槽22的效果。Please refer to FIG. 7, FIG. 8 and FIG. 9. In another embodiment of the present invention, the upper housing 1 is not provided with the aforementioned light shielding wall 10 and the aforementioned opening shielding block 12. Instead, a shielding body 24 is provided at the top of the rotating shaft connecting block 20 of the lower housing 2. A rotating shaft receiving groove 22 is provided at the top of the rotating shaft connecting block 20 of the lower housing 2. 2 is facing upward, so the shielding body 24 is arranged above the opening of the rotating shaft accommodating groove 22 at the top of the rotating shaft connecting block 20, that is, the shielding body 24 replaces the function of the aforementioned opening covering block 12 to limit the rotating shaft 40 of the curved mirror 4, thereby achieving the effect of preventing the rotating shaft 40 from vibrating and falling out of the rotating shaft accommodating groove 22 as mentioned above.

請參閱圖3、圖6及圖9，在前述實施例中皆以旋轉軸容置槽22設置於呈現為長方體的旋轉軸連接塊20的頂部，且皆設置於旋轉軸連接塊20的邊緣區域，並且皆呈現為U形且為開口朝上的態樣作為示範例，藉以方便使用者在僅需由上往下放置將曲面鏡4的旋轉軸40裝入旋轉軸容置槽22，但是實際實施時不限於此，旋轉軸容置槽22的形狀除了可為U形外，也可為局部圓形、正方形、長方形、梯形或正六角形等不同形狀，並且前述形狀的其中一邊作為開口位置，所形成的不同凹槽態樣，但實際實施時形狀也不局限於多邊形，可以根據需求調整旋轉軸容置槽22的形狀，本發明並不特別限制。另外，旋轉軸容置槽22並不限於設置於旋轉軸連接塊20的上方，也可為設置於旋轉軸連接塊20的側邊，而開口遮蓋塊12則可為擺放至對應旋轉軸連接塊20設置旋轉軸容置槽22的側邊的位置，藉以讓開口遮蓋塊12由側邊遮蓋旋轉軸容置槽22的開口。此外旋轉軸容置槽22的開口也不限於朝上的態樣，旋轉軸容置槽22的開口也可為朝向斜前方或斜後方的態樣，本發明並不特別限制。Please refer to FIG. 3, FIG. 6 and FIG. 9. In the above embodiments, the rotation shaft receiving groove 22 is disposed at the top of the rotation shaft connecting block 20 which is a rectangular parallelepiped, and is disposed at the edge area of the rotation shaft connecting block 20, and is presented as a U-shape with the opening facing upward as an example, so that the user can easily place the rotation shaft 40 of the curved mirror 4 from top to bottom into the rotation shaft receiving groove 22. However, In actual implementation, this is not limited to the above. In addition to being U-shaped, the shape of the rotating shaft receiving groove 22 can also be a partial circle, square, rectangle, trapezoid or regular hexagon, and one side of the aforementioned shape is used as the opening position to form different groove patterns. However, in actual implementation, the shape is not limited to a polygon, and the shape of the rotating shaft receiving groove 22 can be adjusted as needed, and the present invention does not specifically limit it. In addition, the rotating shaft receiving groove 22 is not limited to being disposed above the rotating shaft connecting block 20, but may also be disposed on the side of the rotating shaft connecting block 20, and the opening covering block 12 may be placed at a position corresponding to the side of the rotating shaft connecting block 20 where the rotating shaft receiving groove 22 is disposed, so that the opening covering block 12 covers the opening of the rotating shaft receiving groove 22 from the side. In addition, the opening of the rotating shaft receiving groove 22 is not limited to being upward, and the opening of the rotating shaft receiving groove 22 may also be oriented obliquely forward or obliquely backward, and the present invention is not particularly limited thereto.

本發明所提出的抬頭顯示器的結構，相較於先前技術，本發明不僅省去了設置旋轉軸40夾持器的需求，改為讓曲面鏡4的旋轉軸40設置於下殼體2的旋轉軸連接塊20的旋轉軸容置槽22中，並且藉由在上殼體1設置開口遮蓋塊12，或直接在旋轉軸連接塊20上設置遮擋體24的方式，達到對旋轉軸40進行限位的目的。Compared with the prior art, the structure of the head-up display proposed in the present invention not only eliminates the need to set a clamp for the rotating shaft 40, but also allows the rotating shaft 40 of the curved mirror 4 to be set in the rotating shaft accommodating groove 22 of the rotating shaft connecting block 20 of the lower shell 2, and by setting an opening cover block 12 on the upper shell 1, or directly setting a blocking body 24 on the rotating shaft connecting block 20, the purpose of limiting the rotating shaft 40 is achieved.

由於本發明相較於先前技術省去了設置旋轉軸40夾持器的部分，而旋轉軸連接塊20本身也無須占用過多空間，舉例旋轉軸連接塊20可為由旋轉軸40的內側壁向內凸出1~3毫米的塊狀結構，因此本發明相較於先前技術不僅可以省去生產旋轉軸40夾持器的零件的時間成本及金錢成本，與此同時還節省了抬頭顯示器的內部空間，因此能有更大的空間可以設置更大面積的曲面鏡4，藉以提升視野範圍，並且本發明也無須像先前技術一樣必須在抬頭顯示器有限的空間中組裝旋轉軸40夾持器，因此本發明組裝方式相較於先前技術也更加簡單方便，有利於提高製備抬頭顯示器的生產效率。Compared with the prior art, the present invention saves the time and money cost of producing the parts of the rotating shaft 40 clamp, and the rotating shaft connecting block 20 itself does not need to occupy too much space. For example, the rotating shaft connecting block 20 can be a block-shaped structure protruding 1 to 3 mm inward from the inner wall of the rotating shaft 40. Therefore, compared with the prior art, the present invention can not only save the time and money cost of producing the parts of the rotating shaft 40 clamp, but also save the time and money cost of producing the parts of the rotating shaft 40 clamp. At the same time, the internal space of the head-up display is saved, so there is more space to set up a larger curved mirror 4 to improve the field of view. In addition, the present invention does not need to assemble the rotating shaft 40 clamp in the limited space of the head-up display like the previous technology. Therefore, the assembly method of the present invention is simpler and more convenient than the previous technology, which is beneficial to improving the production efficiency of the head-up display.

綜上所述，本發明藉由改良抬頭顯示器的結構，使抬頭顯示器的結構更加簡化，使抬頭顯示器在仍能達到調節曲面鏡的旋轉角度的功能的同時，還具有上述的多項優點，達到節省生產抬頭顯示器的時間成本及金錢成本的效果。In summary, the present invention simplifies the structure of the head-up display by improving the structure of the head-up display, so that the head-up display can still achieve the function of adjusting the rotation angle of the curved mirror while also having the above-mentioned multiple advantages, thereby achieving the effect of saving the time cost and financial cost of producing the head-up display.
