The corresponding HUD display device emits display light from an optical machine, and projects it on the windshield through optical lenses to reflect it to form a virtual image, which produces an enhanced display effect with the real world outside the windshield. However, in the process of manufacturing HUD display equipment, the optical lenses in the equipment are large in size and easy to damage, so smooth turnover on the production line has become a problem.

[0073] The present application will be described in detail below in conjunction with the accompanying drawings, but the content of the description is merely some examples recorded in the present application and does not limit the present application. Changes in structure, method, function, etc. made by ordinary technicians in this field based on these examples are included in the protection scope of the present application.

[0074] It should be noted that the same reference numerals or marks may be used in different examples, but these do not represent an absolute connection in structure or function. In addition, the "first", "second", etc. mentioned in each example are only for the convenience of description, and do not represent an absolute distinction in structure or function, nor can they be understood as indicating or implying the relative importance or the number of corresponding objects. Unless otherwise specified, the "at least one" that may be involved in the description refers to one or more, and "more than one" refers to two or more.

[0075] In addition, when expressing a feature, the character " / " can indicate that there is an or relationship between the front and back associated objects. For example, head-up display / head-up display can be expressed as head-up display or head-up display. When expressing an operation, the character " / " can indicate that there is a division relationship between the front and back associated objects. For example, the magnification M=L / P can be expressed as L (virtual image size) divided by P (image source size). Moreover, the "and / or" in different examples is only to describe the association relationship between the front and back associated objects. This association relationship can include three situations. For example, a concave mirror and / or a convex mirror can be expressed as the existence of a concave mirror alone, the existence of a convex mirror alone, and the existence of both a concave mirror and a convex mirror.

[0076] HUD projection display mainly uses the optical reflection principle to reflect the imaging light to be displayed through a transparent surface into the viewer's eyes. The human eye can see the virtual image information in the opposite direction of the light. Correspondingly, the transparent surface can be the windshield of the vehicle, and the windshield can be used as a display screen to display the navigation information, speed, etc. of the vehicle. Figure 1As shown, the HUD display device may include at least an optical machine 1, a first reflector 2, a second reflector 3, etc., wherein the optical machine 1 includes a backlight source and an image source (not shown), the backlight source is used to provide illumination light and adjust the brightness of the illumination light according to control, for example, the backlight source may be an LED (Light Emitting Diode), a laser, etc. Under the illumination light provided by the backlight source, the image source adjusts the corresponding display content according to control and projects the display light from the surface of the image source, for example, the image source may be an LCD (Liquid Crystal Display), a DMD (Digital Micromirror Devices), a MEMS (Micro-Electro-Mechanical System) micromirror, a LCOS (Liquid Crystal onsilicon), etc. The first reflector 2 and the second reflector 3 can project the display light projected by the optical machine 1 onto the windshield 4, so as to customize the optical path in a smaller space and meet different projection display requirements. The first reflector 2 and the second reflector 3 can be set to concave mirrors, convex mirrors, concave lenses, convex lenses, etc. of other specifications according to the requirements of optical planning, and the surface shape of the lens can adopt a free-form surface. Optionally, at least one of the first reflector 2 and the second reflector 3 can also be adjusted to a certain degree of angle, so as to change the projection position of the display light on the windshield 4 to meet the needs of viewers of different heights. The display light of the optical machine 1 is finally reflected on the windshield 4 of the vehicle to form a virtual image 5. When the human eye 6 observes the virtual image 5 facing the windshield 4, it can feel a certain sense of depth, just like watching a real object at a specific distance outside the windshield. The virtual image 5 can be the navigation information, vehicle speed, etc. as described above. It should be added that, according to the characteristics of different optical machines, the HUD display device can also be provided with a diffuser. In some examples, the HUD display device can also include Fresnel lenses, waveguide optical devices, diffractive optical devices, holographic optical devices, tapered optical fibers, etc.

[0077] HUD display devices can be either aftermarket or front-mounted. Aftermarket HUD display devices are purchased separately based on the user's projection display needs after the user purchases the vehicle. The corresponding HUD display devices are small in size and can be directly placed on the surface of the vehicle's center console for use. Front-mounted HUD display devices are directly embedded in the center console and need to be installed in the space reserved during the vehicle production process. Figure 2As shown, for the HUD display device 100 integrated in the center console of the vehicle, in addition to including the optical engine 1, the first reflector 2, and the second reflector 3, its body is enveloped by the shell 101, and the optical engine 1 and the first reflector 2 and the second reflector 3 are accommodated in the internal space of the shell 101 and are stably fixed to the inside of the shell 101 through a bracket or the like. Figure 1 , the optical machine 1, the first reflector 2, and the second reflector 3 cooperate with each other to realize a certain optical path planning inside the shell 101, and finally project the display light through the projection window 102 opened in the shell 101. When the HUD display device 100 is embedded in the center console of the car, the projection window 102 on the shell 101 is facing the vehicle windshield above the center console. Accordingly, the display light projected from the projection window 102 will be reflected on the windshield to form a virtual image that can be seen by the human eye. In this example, there are two optical lenses inside the HUD display device, so the two optical lenses need to be installed separately during the production process, and there is also a process of transporting the two optical lenses from the warehouse to the production line before installation. These optical lenses are usually large in size. Once they are slightly bumped or deformed during the transportation process, they will seriously affect the projection display effect of the HUD display device. Therefore, there are high requirements for the personnel who transport the optical lenses, and it is urgent to make up for the shortcomings of personnel operation by improving the transportation tools.

[0078] In some examples, such as Figure 3As shown, the optical lens transport tool 20 includes a base 21 at the bottom and a cabinet 22 at the top, and the base 21 supports the cabinet 22. In this example, the bottom surface of the cabinet 22 is smaller than the base 21, so that the upper surface of the base 21 is partially connected to the cabinet 22, and partially exposed to the outside of the cabinet 22 to form an outer platform 211. Accordingly, the outer platform 211 can provide a transitional platform for the loading and unloading of optical lenses. For example, the optical lenses to be loaded can be temporarily placed on the outer platform 211, and then placed one by one into the interior of the cabinet 22. Optionally, a mechanical arm 23 can also be set on the outer platform 211, and the mechanical arm 23 can replace manpower to place the optical lenses into the interior of the cabinet 22, so as to avoid the constraints on the handling personnel caused by the excessive height of the cabinet 22. In some examples, casters 212 are provided at the bottom of the base 21, and the entire optical lens transport tool 20 is parked on the ground by the casters 212. At the same time, the casters 212 can also move the optical lens transport tool 20, which is convenient for the turnover of optical lenses between the warehouse and the production line. Optionally, the casters 212 are universal wheels, which can support complex turning and other movement requirements. Accordingly, the casters 212 can also be connected to a motor, which can support one-key start, and the optical lens transport tool 20 automatically moves from the warehouse to the production line or from the production line to the warehouse. In some examples, the upper, lower, left and right sides of the cabinet 22 are surrounded by side panels 223 to form a closed internal space, and only one side is an opening set as the cabinet opening of the cabinet 22, and accordingly, the cabinet opening is facing the direction of the outer platform 211. Optionally, corresponding operating rules or regulations and other labels can be pasted on the outer surface of the side panel 223, and further, a control button 222, such as a physical button or a touch screen button, can be set on the side panel 223. The control button 222 is connected to the internal integrated control system and can control the corresponding motor, such as the caster 212 on the base 21 to control the movement of the direction or path. In order to prevent the optical lens transport tool 20 from being contaminated by external dust on the internal optical lens during movement, a dust curtain 221 can be set at the cabinet opening of the cabinet 22. The dust curtain 221 can be opened when loading and unloading the optical lens, and closed when the optical lens transport tool 20 moves. Optionally, the dust curtain 221 can be driven by a motor, and the operator can use the control button 222 to implement specific operations.

[0079] like Figure 4As shown, when the dust curtain 221 is fully opened, the cabinet opening is fully exposed. Looking inward from the cabinet opening, the internal space of the cabinet 22 is divided into several layers by several layers 224. Each layer can carry several optical lenses, which greatly improves the utilization efficiency of the internal space of the cabinet 22. In some examples, when the optical lens transport tool 20 is moved to the side of the production line, the control button 222 can be used to control the casters to make the cabinet opening of the cabinet 22 face the production line. At this time, the casters can also be controlled to lock to prevent the optical lens transport tool 20 from moving back and forth during loading and unloading. If it is necessary to remove the optical lens from the cabinet 22, the optical lenses of each layer can be removed one by one by the mechanical arm 23, especially the optical lenses of the high-rise. The mechanical arm 23 can greatly improve the reliability of loading and unloading. Optionally, the mechanical arm 23 can also be used to load the optical lenses into the cabinet 22 layer by layer. In some examples, the robot arm 23 is realized by a person operating the control button 222. Specifically, the control button 222 includes a start / stop button, which can start or stop the operation of the robot arm 23 with one button, and the robot arm 23 can grab the optical lens according to a preset program. Optionally, the control button 222 can also include direction keys for controlling the up, down, left, right, forward, and backward directions of the robot arm 23, and the control personnel can realize specific operations. Figure 5 , Figure 6 As shown, the robot arm 23 includes a rotating joint 231 and a grabbing end 232. The rotating joint 231 can be rotated to make the grabbing end 232 in different positions and grabbing angles to adapt to different positions of the optical lens and different layers corresponding to loading and unloading on the cabinet. The grabbing end 232 is directly responsible for the handling of the optical lens, thereby replacing the manual handling. Figure 5 As shown, the gripping end 232 is provided with a clamping claw, such as Figure 6 As shown, the gripping end 232 is provided with a suction cup. Accordingly, the gripping end 232 can directly grasp or suck the optical lens, load it from the outside onto each layer of the cabinet 22, or take it out from each layer of the cabinet 22 and put it into the production line or the operator's hand. Optionally, the gripping end 232 may not directly carry the optical lens, but grasp or suck the lens holder that is engaged with the optical lens. Specifically, the lens holder includes a groove that is just engaged with the optical lens inside and a handle structure that cooperates with the gripping end 232 outside. The gripping end 232 grasps or sucks the corresponding handle structure, so that the lens holder is picked up together with the optical lens. At this time, the optical lens is in a ready-to-engage state in the lens holder, and will not shake as the mechanical arm 23 moves. This can protect the optical lens from being damaged by the mechanical arm 23 on the one hand, and on the other hand, the structural shape of the gripping end 232 can be standardized to flexibly adapt to optical lenses of different types and sizes.

[0080] Furthermore, in order to achieve orderly placement and traceability of each layer of optical lenses in the cabinet 22, as Figure 7As shown, taking the first layer as an example, the layer 224 includes a guide rail 225 and a loading platform 226 that moves on the guide rail 225. The loading platform 226 can receive an external optical lens and carry the optical lens to move on the layer 224 along the guide rail 225. Figure 4 , the shelf 224 has a portion close to the cabinet opening and an internal space enclosed by the side panels 223 relative to the cabinet body 22. Since the internal space is protected by the side panels 223, the optical lens can be placed in the internal space to reduce the intrusion of external dust, and the effective use of the internal space can increase the number of optical lenses. However, in the prior art, if the optical lens is carried by manpower alone, especially in the internal space of the high-rise, it may be difficult for the carrier's arms to reach it, and the optical lens cannot be reliably placed in the cabinet body. In this example, the guide rail 225 is used to extend to the inner space of the layer board, and the loading platform 226 is used to realize the internal and external connection. Accordingly, the guide rail 225 set on the layer board 224 is divided into a loading area located at the cabinet opening of the cabinet 22 and a buffer area located inside the cabinet 22. The loading area is used for loading and unloading optical lenses, that is, the loading platform 226 can be moved to the loading area to receive the optical lenses put in from the outside or remove the optical lenses it carries and unload them to the external production line. The buffer area is used to temporarily store the optical lenses when the optical lens transport tool 20 moves, that is, the loading platform 226 can carry the optical lenses along the guide rail from the loading area to the buffer area and realize temporary parking. Optionally, the two ends of the guide rail are the first end and the second end, respectively, and the first end and the second end are both in the loading area. The first end can be used to load the optical lenses, and the second end can be used to unload the optical lenses, and the functional settings are divided. In some examples, a fixed structure is provided between the loading platform 226 and the optical lens, and the fixed structure can be used for the loading platform 226 to carry the optical lens. Specifically, when the loading platform 226 moves on the guide rail, the optical lens can be stabilized by the fixed structure to prevent the optical lens from shaking and protect the optical lens from damage. Optionally, the fixed structure provided on the loading platform 226 is a buckle that cooperates with the lens holder. After the optical lens is in a snap-fit ​​ready state in the lens holder, it can be placed on the loading platform by a mechanical arm. At this time, the lens holder can be automatically fixed with the buckle on the loading platform 226, so that the lens holder and the optical lens will not easily fall off from the loading platform 226, thereby improving stability. When removing, the buckle can also be easily operated to remove the lens holder together with the optical lens.

[0081] like Figure 8As shown, the guide rail 225 provided on the layer plate 224 specifically includes a first guide rail 2251 and a second guide rail 2252. The first guide rail 2251 and the second guide rail 2252 both support the movement of the loading platform 226 and the corresponding buffering function. In some examples, the loading platform 226 is in contact with the first guide rail 2251 and the second guide rail 2252 through a mobile drive device such as a roller, and the mobile drive device can drive the loading platform 226 to move on the first guide rail 2251 and the second guide rail 2252. Optionally, the mobile drive device can be connected to a corresponding motor, Figure 4 The control button 222 in can also control the operation of the mobile drive device, such as specifically controlling the movement direction and movement speed of a specific loading platform 226 on the first guide rail 2251 and the second guide rail 2252, so that the loading platform 226 carrying the optical lens can be directed from the loading area to the buffer area or the loading platform 226 to be unloaded from the buffer area can be moved to the loading area, and the loading platform 226 can be controlled to switch between the first guide rail 2251 and the second guide rail 2252. In some examples, the loading platform 226 is also provided with a braking device, which can cooperate with the mobile drive device to control the mobility of the loading platform 226 on the guide rail. When the loading platform 226 moves to the designated parking position in the buffer area, the braking device can be activated, so that the loading platform 226 can be firmly parked on the guide rail without slipping, thereby playing a role in storing the optical lenses. Optionally, Figure 4 The control button 222 in the control panel can also control the start and stop of the brake device, and the operator controls the parking position of the loading platform 226. In a specific example, the first guide rail 2251 and the second guide rail 2252 support a plurality of loading platforms 226 to move and park thereon, and accordingly support a plurality of optical lenses.

[0082] In some examples, the two ends of the first guide rail 2251 and the second guide rail 2252 are connected to form a whole, so that the first guide rail 2251 and the second guide rail 2252 will form two closed circulation guide rails. After the two ends of the guide rails are connected at one position, the loading platform 226 can always return to the origin when moving in the same direction along the guide rails. In this way, when there are multiple loading platforms 226 on the guide rails, the first-in-first-out effect can be achieved. When the loading platform 226 needs to be unloaded again after loading the optical lens, it does not need to return to the original path, so the rear loading platform 226 does not need to give way to the front loading platform 226. Fig. 9As shown, the first guide rail 2251 is a circular guide rail connected end to end. The first guide rail 2251 includes a loading area 201 (i.e., the position facing the cabinet opening) and a buffer area outside the loading area 201 (i.e., the position for temporary storage of optical lenses). When it is necessary to load optical lenses into the cabinet, the specific loading platform 226 can be controlled to move to the loading area 201 to load the optical lenses. Specifically, the loading of the optical lenses can be realized by referring to the fixed structure in the above example. After completing the loading of the optical lenses, the loading platform 226 can move along the guide rail to a designated position in the buffer area. In this example, the loading platform 226 moves clockwise along the guide rail. The top position of the first guide rail 2251 can correspond to the innermost space of the cabinet, and the loading platform 226 can move to the inner position along the guide rail. When the optical lens transport tool needs to be transferred between the warehouse and the production line, the loading platform 226 can be fixed on the guide rail under the action of the brake device. When the optical lens in the cabinet needs to be taken out, the brake device can be closed again and the loading platform 226 can be controlled to continue to move clockwise along the guide rail until it reaches the loading area 201 again. In the example with multiple loading platforms 226, all loading platforms 226 move clockwise synchronously and arrive at the loading area 201 in turn. The loading platform 226 can unload the optical lens on it in the loading area 201, and then load a new optical lens. Since the optical lens that enters first is unloaded first, it can be installed on the production line according to the original numbering order, which improves the convenience of management.

[0083] like Figure 8As shown, in some examples, the first guide rail 2251 and the second guide rail 2252 are both circulating guide rails, and the second guide rail 2252 is located in the inner circle of the first guide rail 2251. In this example, only the first guide rail 2251 has a loading area, that is, the optical lenses are uniformly loaded and unloaded on the first guide rail 2251, and the second guide rail 2252 is only used as a part for caching optical lenses, which can increase the efficiency of the use of the internal space of the cabinet. As mentioned above, the cached optical lenses are parked at the designated position of the guide rail through the loading platform 226. Therefore, if the optical lenses are stored on the second guide rail 2252, it is necessary to set a path for the loading platform 226 to reach the second guide rail 2252 from the first guide rail 2251. Accordingly, a switch 227 is set between the first guide rail 2251 and the second guide rail 2252. The switch 227 is used to switch the guide rail where the loading platform 226 is located. In this example, two switches 227 are arranged between the first guide rail 2251 and the second guide rail 2252. The two switches 227 are symmetrical in position, so that a more flexible planning path can be provided for switching the guide rails of the loading platform 226. The switch 227 specifically includes a cross-line guide rail 2271, a cross-line guide rail 2272, a cross-line guide rail 2273, a rotating platform 2274 for controlling the rotation of the cross-line guide rail 2272, and a rotating platform 2275 for controlling the rotation of the cross-line guide rail 2273. The rotating platforms 2274 and 2275 can rotate at different angles under the control of the motor, for example, Figure 4 The control button 222 in the figure is operated to rotate, so that the cross-line guide rails 2272 and the cross-line guide rails 2273 are clamped at different angles and docked with different guide rails to achieve different guide rail switching functions. In this example, the cross-line guide rail 2271 is perpendicular to the first guide rail 2251 and the second guide rail 2252, and serves as a transition guide rail for the loading platform 226 to switch to other tracks, and cooperates with the cross-line guide rails 2272 and the cross-line guide rails 2273 to form a continuous switching path. The different paths formed at different rotation angles will be described in detail below.

[0084] like Fig. 9 As shown, the rotating platform drives the cross-line guide rail to rotate so that there is no connecting path between the first guide rail 2251 and the second guide rail 2252, that is, Figure 8 The cross-line rail 2272 is connected to the first rail 2251, and the cross-line rail 2273 is connected to the second rail 2252, and neither is connected to the cross-line rail 2271. Therefore, the loading platform 226 on the first rail 2251 can only move on the first rail 2251, and the loading platform 226 on the second rail 2252 can only move on the second rail 2252, and the two do not interfere with each other. In addition, the loading area 201 is set on the first rail 2251, so the newly loaded optical lens is first loaded into the buffer area of ​​the first rail 2251. Fig.10 As shown, in Fig. 9Based on the example, when the loading platforms 226 on the first rail 2251 are all loaded with optical lenses, the loading platforms 226 on the second rail 2252 need to be moved to the loading area 201 on the first rail 2251 to load the optical lenses. At this time, the switch between the first rail 2251 and the second rail 2252 can be driven so that the rotation of the cross-line rail can be connected to the first rail 2251 and the second rail 2252 respectively. In this example, only one of the two switches between the first rail 2251 and the second rail 2252 realizes the cross-line connection, while the other switch maintains the connection inside the rail, so the loading platform 226 starting from the loading area 201 can enter the second rail 2252 from the switch close to the loading area 201. Since the turnout in this example is connected to the right half of the second guide rail 2252, the loading platform 226 enters the second guide rail 2252 by first moving from the right half and then moving counterclockwise around the second guide rail 2252. Specifically, the buffer can be realized at any position of the second guide rail 2252. Fig.11 As shown, if the optical lenses cached on the second rail 2252 need to be unloaded outside the cabinet in the loading area 201, the switch can be switched again to connect the switch directly to the left half of the second rail 2252. At this time, the loading platform 226 that first enters the second rail 2252 can reach the first rail 2251 along the cross-line rail, and finally move to the transfer area 201 to realize the unloading of the optical lenses. Fig.12 As shown, the loading platform 226 on the first guide rail 2251 and the second guide rail 2252 can also have more moving paths. In this example, the two switches between the first guide rail 2251 and the second guide rail 2252 are connected by cross-line connection. Specifically, the switch close to the loading area 201 is connected to the right half of the first guide rail 2251 and the second guide rail 2252, respectively, and the other switch is also connected to the right half of the first guide rail 2251 and the second guide rail 2252, which is equivalent to setting an entrance and an exit between the two guide rails for the second guide rail 2252, and the right half of the first guide rail 2251 and the right half of the second guide rail 2252 form a closed circulation path, and the loading platform 226 can move counterclockwise or clockwise along this circulation path from the loading area 201. Accordingly, the loading platform 226 carrying the optical lens can enter the second rail 2252 from the first switch, and can be temporarily cached on the second rail 2252 as needed. When the corresponding loading platform 226 on the second rail 2252 needs to unload the optical lens, it can reach the first rail 2251 through the second switch, and then further move to the loading area 201 to unload the optical lens. Fig.13 As shown, in Fig.12Based on the example, in order to make good use of the space in the left half of the second rail 2252, the above two switches can be switched so that the switch close to the loading area 201 is connected to the right half of the first rail 2251 and the left half of the second rail 2252 respectively, and the other switch is also connected to the right half of the first rail 2251 and the left half of the second rail 2252 respectively. In this way, a closed loop path can be formed between the first rail 2251 and the second rail 2252. At this time, the loading platform 226 on the loading area 201 can reach the left half of the second rail 2252, and the loading platform 226 on the left half of the second rail 2252 can be switched to the first rail 2251 and finally moved to the loading area 201 to realize the unloading of the optical lens. It should be noted that due to the flexibility of the switch switching in this example, more path combinations can be realized to meet the caching and in-and-out management of the required optical lenses in the actual handling scenario, and ensure the traceability of the optical lenses during the handling process.

[0085] In summary, the present application has a cabinet on the base, and the interior of the cabinet is divided into multiple layers of space by layers, and the loading platform and the guide rails on each layer are used to easily move the optical lenses to be transported from the outside of the cabinet to the inside of the cabinet, and can reliably cache them at a position far away from the cabinet opening, avoiding the influence of the cabinet height and other factors on the difficulty of the loading process, and maximizing the use of the internal space to load as many optical lenses as possible. The present application can realize convenient optical lens caching and transportation, and improve the production efficiency of HUD display equipment.
