Description

Technical Field

[0001] This disclosure relates to head-up display devices and vehicles having said head-up display devices. Background Technology

[0002] In modern automotive technology, head-up displays (HUDs) have become crucial components for enhancing driving safety and comfort. By projecting key driving information, such as vehicle speed, navigation instructions, and fuel level, directly onto the windshield, HUDs allow drivers to access this information without frequently shifting their gaze. This design reduces driver distraction caused by checking the instrument panel, thereby improving driving safety.

[0003] However, despite the progress made in the design and functionality of existing head-up display devices, some problems still exist. For example, the inherent vibration frequency of head-up display devices is relatively low, which can easily cause resonance, thus requiring higher structural strength. In addition, the adjustment of the reflectors in head-up display devices is inconvenient, and the overall cost of the equipment is relatively high.

[0004] The present disclosure aims to provide a head-up display device that can solve these problems. Summary of the Invention

[0059] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0060] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of this disclosure may have fewer components, other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0061] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, “an” or “a” and similar terms do not necessarily indicate a quantity limitation. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the element or object listed following the word and its equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, which may change accordingly when the absolute position of the described object changes.

[0062] A head-up display (HUD) typically includes an image generation unit and a reflector. The image generation unit generates the HUD output image and may consist of a light source, optical films, and other optical components. The reflector reflects the image generated by the image generation unit onto the windshield. The reflector can rotate about an axis within the HUD.

[0063] The angle of the head-up display (HUD) mirror is adjustable. One scenario requiring mirror angle adjustment is initial setup on the assembly line at the OEM (Original Equipment Manufacturer), where minor adjustments might be made to accommodate manufacturing tolerances for different vehicles. Another scenario involves user adjustment during vehicle use. For example, a driver might adjust the mirror angle based on their height, posture, and line of sight to ensure the image is within the optimal field of vision. Drivers can also adjust the mirror angle based on changes in external light caused by different driving environments and weather conditions to adjust image brightness and contrast, ensuring clear image visibility. Furthermore, drivers may dynamically adjust the HUD mirror angle based on changes in vehicle speed.

[0064] This disclosure aims to achieve one or more of the following objectives by providing a mirror adjustment system: reducing the cost of the adjustment system and the overall device; increasing the frequency of the head-up display device to make its structure stable and able to withstand a high natural frequency, avoiding resonance effects; and making the mirror of the head-up display device easy to adjust.

[0065] The following description, in conjunction with the accompanying drawings, describes the head-up display device of this disclosure, particularly the adjustment system of the head-up display device. Figure 1 and Figure 2 A partial view of a heads-up display device is shown, including the adjustment system. Figure 3 A general view of the head-up display device is shown. In the embodiment shown in the figures, the head-up display device includes a housing 50 and a reflector (not shown) and an adjustment plate 40 located within the housing 50. The specific structure of the housing 50 of the head-up display device is not limited, and it may be a one-piece housing 50 or composed of multiple housing 50 parts. The housing 50 may be provided with mounting portions for mounting to a vehicle.

[0066] The reflector is fixed relative to the adjusting plate 40, for example, it can be directly fixed to the adjusting plate 40. The adjusting system for adjusting the adjusting plate 40 includes a first adjusting mechanism 10, a second adjusting mechanism 20, and a third adjusting mechanism 30, each of which can operate independently. Each of the three adjusting mechanisms engages with the adjusting plate 40 to adjust the angle of the adjusting plate 40, thereby changing the angle of the reflector. The way the first adjusting mechanism 10, the second adjusting mechanism 20, and the third adjusting mechanism 30 engage with the adjusting plate 40 is not limited, as long as they can drive the adjusting plate 40 to move accordingly. Specifically, for example... Figure 2 As shown, the three adjustment mechanisms of this disclosure are arranged in a triangular form, particularly an isosceles triangle, wherein the third adjustment mechanism 30 is located between the first adjustment mechanism 10 and the second adjustment mechanism 20 and is offset by a certain distance relative to the line connecting the first adjustment mechanism 10 and the second adjustment mechanism 20.

[0067] In this disclosure, the statement that "the third adjusting mechanism 30 is offset from the line connecting the first adjusting mechanism 10 and the second adjusting mechanism 20 by a certain distance" aims to illustrate that the three adjusting positions of the three adjusting mechanisms that engage with the adjusting plate 40 are not aligned in a straight line, but rather arranged in a triangle. The line connecting the first adjusting mechanism 10 and the second adjusting mechanism 20 can be understood as the line connecting the center points of the adjusting positions of the first adjusting mechanism 10 and the second adjusting mechanism 20. This arrangement allows for simple and effective adjustment of the angle of the adjusting plate 40. For example, when the first adjusting mechanism 10 and the second adjusting mechanism 20 are stationary, by pushing the adjusting plate 40 forward or pulling it backward with the third adjusting mechanism 30, the angle of the adjusting plate 40 can be adjusted relative to the first adjusting mechanism 10 and the second adjusting mechanism 20. Figure 2The axis of rotation is shown in dashed lines. The first adjustment mechanism 10 and the second adjustment mechanism 20 define the axis of rotation of the adjustment plate 40. By adjusting the positions of the first adjustment mechanism 10 and the second adjustment mechanism 20, the position of the axis of rotation of the adjustment plate 40 can be changed.

[0068] The distance by which the third adjustment mechanism 30 is offset from the line connecting the first adjustment mechanism 10 and the second adjustment mechanism 20 can be, for example, one-half or one-third of the width of the adjustment plate 40.

[0069] The first adjusting mechanism 10 and the second adjusting mechanism 20 are preferably the same type of adjusting mechanism, referred to here as the first type of adjusting mechanism, and the third adjusting mechanism 30 is a second type of adjusting mechanism, which is different from the first type of adjusting mechanism. Setting the first adjusting mechanism 10 and the second adjusting mechanism 20 as the same type of adjusting mechanism can reduce the number of parts, simplify the structure, and reduce structural complexity and cost, while the second type of adjusting mechanism, which is different from the first type of adjusting mechanism, can improve the overall adjusting performance of the adjusting system.

[0070] Both the first and second type adjustment mechanisms include a base, a rod, and a mounting portion. For ease of distinction, the base, rod, and mounting portion of the first adjustment mechanism 10 can be referred to as the first base 11, the first rod 12, and the first mounting portion 13, respectively; similarly, the base, rod, and mounting portion of the second adjustment mechanism 20 can be referred to as the second base 31, the second rod 32, and the second mounting portion 33, respectively. Figure 5 The first base 11 and the first lever 12 of the first type of adjustment mechanism are shown. Figure 6 The first mounting part 13 of the first type of adjustment mechanism is shown. Figure 7 The second base 31 and the second lever 32 of the second type of adjustment mechanism are shown. Figure 8 The second mounting part 33 of the second type of adjustment mechanism is shown.

[0071] Both the first and second type of adjustment mechanisms have a base that is fixed relative to the head-up display device (e.g., the head-up display device housing 50) during the adjustment process, and a mounting portion that is fixed relative to the adjustment plate 40. (See appendix.) Figures 5-8 The rod is engaged with both the base and the mounting portion. The rod is engaged with the base in a manner that allows it to move relative to the base. For example, in the embodiment shown in the drawings, the rod extends through the base and is configured such that, when the base is rotated, the rod can move relative to the base in two directions along its axis. The end of the rod, i.e., the end of the rod near the adjusting plate 40, is connected to the mounting portion, such that movement of the rod along its axis causes movement of the mounting portion, which in turn causes corresponding movement of the adjusting plate 40, which is fixedly connected to the mounting portion.

[0072] In a preferred embodiment, the connection between the rod and the mounting part is not a fixed connection, but a movable connection. For example... Figures 5-8 As shown, both the first and second type of adjusting mechanisms can have a ball head at the end of their levers. The ball heads of the first lever 12 and the second lever 32 can be referred to as the first ball head 121 and the second ball head 321, respectively, and are respectively housed in the receiving portion 131 of the first mounting portion and the receiving portion 331 of the second mounting portion. The respective ball heads can rotate in their respective receiving portions, thereby forming a movable connection between the lever and the mounting portion.

[0073] The movable connection between the lever and the mounting part differs for the first type and the second type of adjusting mechanism. For example... Figure 5 , 6 As shown, the first ball head 121 of the first type of adjustment mechanism is housed in the receiving portion 131 of the first mounting portion in a manner that allows it to rotate only relative to the first mounting portion 13. Therefore, the receiving portion 131 of the first mounting portion is preferably in the form of a spherical receiving space. For the second type of adjustment mechanism, such as... Figure 7 , 8 As shown, the second ball head 321 is accommodated in the receiving portion 331 of the second mounting portion in a manner that allows it to both rotate and translate relative to the second mounting portion 33. Therefore, the receiving portion 331 of the second mounting portion is preferably configured as a channel, within which the second ball head 321 can rotate and move along. For both types of adjustment mechanisms, the different movable connection methods of the lever and mounting portion allow for more efficient and flexible adjustment of the overall adjustment mechanism at a low cost.

[0074] It should be noted that the preferred embodiment of this disclosure is that the first ball head 121 of the first type of adjustment mechanism can only rotate relative to the first mounting portion 13, while the second ball head 321 of the second type of adjustment mechanism can both rotate and translate relative to the second mounting portion 33. In other embodiments, the first ball head 121 of the first type of adjustment mechanism can also be designed to both rotate and translate relative to the first mounting portion 13. This allows both types of adjustment mechanisms to use the same mounting portion, simplifying the types of parts. In such an embodiment, the channel of the second mounting portion can be arranged along the width of the adjustment plate, and the channel of the first mounting portion can be arranged along the length of the adjustment plate.

[0075] The three mounting parts can be fixed to the adjusting plate 40 in various ways. Preferably, such as... Figure 1 As shown, the adjusting plate 40 is provided with three cylindrical receiving seats 41 for receiving various mounting parts. Preferably, each receiving seat 41 is integrally formed with the adjusting plate 40. Figure 6 ,8 As shown, the mounting portions 13 and 33 may be provided with receiving portions 131 and 331 at the first end, and the other end may be used as an insertion end for insertion into the receiving base 41.

[0076] In the preferred embodiment shown in the accompanying drawings, at least one of the first type of adjustment mechanism and the second type of adjustment mechanism, preferably both, has a manual adjustment feature to adjust the position of the corresponding lever relative to the corresponding base. Figure 4 An exemplary structure of a manual adjustment feature installed on the first adjustment mechanism 10 or the second adjustment mechanism 20 is shown, but it can also be used in the third adjustment mechanism 30. The function of the manual adjustment feature is to allow manual adjustment of the adjustment mechanism. In other words, the manual adjustment feature allows manual change of the longitudinal position of the lever relative to the base, thereby adjusting the adjustment plate 40. "Manual" adjustment includes adjustment performed by hand and adjustment using hand tools.

[0077] like Figure 4 As shown, the manual adjustment feature includes an adjustment gear 111 fixed to or integral with the first base 11, thereby allowing the first base 11 to be rotated by manually rotating the adjustment gear 111. Preferably, the adjustment gear 111 is a bevel gear surrounding the first base 11 to facilitate engagement with a tool 60 oriented perpendicular to the first base 11. The tool 60 can be a handheld external tool or a force transmission component adjusted by an external tool.

[0078] The first rod portion 12 is mounted to the first base portion 11 such that rotation of the first base portion 11 can cause the first rod portion 12 to move forward or backward along its axial direction while rotating with it. Specifically, as shown... Figure 4-5 As shown, the first rod portion 12 extends through the first base portion 11. The first rod portion 12 also has one or more extensions 123 extending radially from it. In the embodiment shown in the figures, the first rod portion 12 has four extensions 123 forming a generally cross shape. Correspondingly, the end of the first base portion 11 has a cross-shaped opening, so that rotation of the first base portion 11 will drive rotation of the first rod portion 12. Synchronous rotation of the first rod portion 12 and the first base portion 11 can also be achieved through other features different from the extensions 123. The first rod portion 12 is also provided with a threaded section 122, which engages with corresponding threaded sections of other components of the head-up display device, for example, with corresponding threaded sections on the housing 50. Thus, when the first base portion 11 rotates, the first rod portion 12, driven by the first base portion 11, will move forward or backward along its length direction while rotating, thereby achieving adjustment.

[0079] like Figure 5As shown, preferably, an annular cover 14 may also be provided around the first base 11, and the annular cover 14 is provided with a through hole to allow external tools to easily engage the adjusting gear 111 covered by the annular cover 14.

[0080] Figure 7 The second base 31 and the second lever 32 of the second type of adjustment mechanism in the exemplary embodiment are shown. The manual adjustment mechanism may further include a manual adjustment component 35 that meshes with an adjustment gear. One end of the manual adjustment component 35 meshes with the adjustment gear 111, and the other end is provided with a hexagonal nut. Convenient manual adjustment can be achieved by manually rotating the hexagonal nut.

[0081] Figure 9 A manual adjustment feature according to another embodiment is shown. Compared to Figure 4 The manual adjustment feature shown is in Figure 9 In the illustrated embodiment, the manual adjustment feature further includes an intermediate transmission member 15, which has a longitudinal body and a first transmission gear 151 is provided at a first end of the longitudinal body, and a second transmission gear 152 is provided at the other end. The first transmission gear 151 meshes with the adjustment gear 111, and the second transmission gear 152 is used for manual adjustment, for example, meshing with a hand tool 60. The intermediate transmission member 15 allows for the provision of a through hole at a suitable location to allow the insertion of the tool 60, for example... Figure 9 In this way, the tool 60 is allowed to pass through the appropriate position of the vehicle component 51 around the head-up display device.

[0082] Preferably, in Figure 4 In one embodiment, the end gear of tool 60 that meshes with adjusting gear 111 is a bevel gear. Similarly, Figure 9 In one embodiment, the first transmission gear 151 that cooperates with the adjusting gear 111 is preferably also a bevel gear.

[0083] In the preferred embodiment shown in the accompanying drawings, the second type of adjustment mechanism, in addition to manual adjustment, also includes an electric adjustment mechanism utilizing a motor 34. Specifically, as follows... Figure 2 As shown in Figure 7, the second type of adjustment mechanism further includes a motor 34, which is used to adjust the position of the second lever 32. The motor 34 is preferably installed at a position away from the adjustment plate 40 in the second type of adjustment mechanism, and can be configured to directly or indirectly drive the second lever 32 to move.

[0084] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
