Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically to a calibration device. Background Technology

[0002] To ensure safer and more stable driving, an increasing number of vehicles are equipped with head-up displays (HUDs). HUDs can overlay various information, such as navigation, driving, and environmental information, onto the driver's field of vision, preventing the driver from looking down at information and deviating from the road, thus avoiding dangerous driving consequences. The display method of a HUD generally involves converting the information to be displayed into a magnified virtual image and then projecting it onto the windshield in front of the driver, who then sees the displayed information on the windshield. Because the imaging position, imaging area, and imaging effect of the HUD significantly affect the user experience, it is necessary to verify and calibrate the imaging position, imaging area, and imaging effect of the HUD during the vehicle development phase, using the overall vehicle posture.

[0003] In related technologies, each calibration device can only calibrate the imaging position, imaging area, and imaging effect of the head-up display for one type of vehicle. Once the vehicle model is changed, a calibration device matching the new model needs to be installed. In other words, the applicability of this type of calibration device is relatively small.

Detailed Implementation

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0056] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0057] Combination Figures 1 to 2 As shown in the figure, this application embodiment provides a calibration device, which includes a base 100, a support component 200 and a calibration plate 300.

[0058] The base 100 is connected to a locking component 110. When the locking component 110 is in the unlocked state, the position of the base 100 is movable; when the locking component 110 is in the locked state, the position of the base 100 is fixed. In other words, the position of the base 100 can be adjusted to any position and can be fixed by the locking component 110.

[0059] One end of the support assembly 200 is connected to the base 100, and the other end of the support assembly 200 extends away from the base 100. The support assembly 200 has multiple first mounting holes 210 in the extending direction. The calibration plate 300 includes a first surface 310 and a second surface 320 facing away from each other. The first surface 310 is connected to the support assembly 200 at any of the first mounting holes 210, and the second surface 320 is suitable for arranging a preset image. It should be noted that the first surface 310 and the second surface 320 can be parallel to each other. The support assembly 200 and the base 100 can be fixed together by bolts, pins with rings and bolts, thereby facilitating assembly and disassembly, and reducing the storage space of the calibration device after disassembly. The second surface 320 has multiple scale lines in both the horizontal and vertical directions. The distance between two adjacent scale lines in the horizontal direction can be 0.5 mm, and the distance between two adjacent scale lines in the vertical direction can also be 0.5 mm, thereby allowing for more precise adjustment of the position of the calibration plate 300 and the position of the preset image arranged on the second surface 320.

[0060] It should be noted that the calibration device provided in this application embodiment can be applied in real-vehicle calibration or bench calibration scenarios during the vehicle development process. It is a device for calibrating the imaging results of a head-up display (HUD) in a vehicle. The imaging results include the imaging position, imaging area, and imaging effect. During real-vehicle calibration or bench calibration, the HUD is typically activated to simulate the HUD's operation under normal vehicle conditions. The calibration device is generally placed at a preset imaging position in front of the HUD. Different vehicle models correspond to different preset imaging positions; for example, the height or horizontal position of the preset imaging position may differ between different vehicle models. The target image generated by the HUD is projected onto the second surface 320 of the calibration plate 300, thus displaying the target image generated by the HUD on the calibration plate 300. Preset images are arranged on the second surface 320, for example, a pre-made preset image corresponding to the vehicle model at the preset imaging position is printed on paper, and the paper with the preset image is pasted onto a designated position on the calibration plate 300. The preset image and the target image are compared one by one. When the position of the target image and the preset image deviates, or when the target image is distorted or ghosted relative to the preset image, the angle or position of the head-up display needs to be adjusted accordingly until the target image and the preset image coincide. This completes the verification and correction process of the head-up display during the actual vehicle calibration or bench calibration.

[0061] Using the calibration device provided in this application embodiment, since the support component 200 is connected to the base 100 and the calibration plate 300 respectively, when the locking component 110 is in the unlocked state, the calibration plate 300 can be moved by moving the base 100, that is, the horizontal position of the calibration plate 300 can be adjusted arbitrarily. Meanwhile, the base 100 is generally located on the ground, and the heights of the various first mounting holes 210 on the support component 200 from the ground are different. By connecting the calibration plate 300 to the first mounting holes 210 at different positions, the distance between the calibration plate 300 and the base 100 can be adjusted, that is, the height of the calibration plate 300 relative to the ground can be adjusted arbitrarily. Therefore, using the calibration device provided in this application embodiment, the horizontal position and the height relative to the ground of the calibration plate 300 can be adjusted arbitrarily, thereby meeting the needs of different vehicle models in the head-up display imaging calibration process, and also meeting the calibration needs corresponding to different eye positions in different vehicle models, making the calibration device widely applicable.

[0062] The following is in conjunction with the appendix Figures 1 to 3 The details and functions of the calibration device provided in the embodiments of this application will be described in more specific and detailed manner.

[0063] like Figure 1As shown, in some embodiments, the base 100 includes a body 120, a first connector 130, a second connector 140, a third connector 150, and a fourth connector 160. One end of the first connector 130 and one end of the second connector 140 are connected to one end of the body 120, forming a first preset angle. One end of the third connector 150 and one end of the fourth connector 160 are connected to the other end of the body 120, forming a second preset angle. The first preset angle and the second preset angle are equal. The first connector 130, the second connector 140, the third connector 150, and the fourth connector 160 extend in a direction away from the body 120. The first connector 130 and the third connector 150 are on the same straight line, and the second connector 140 and the fourth connector 160 are on the same straight line.

[0064] The locking assembly 110 includes a first locking member 111, a second locking member 112, a third locking member 113, and a fourth locking member 114. The first locking member 111 is connected to the first connecting member 130, the second locking member 112 is connected to the second connecting member 140, the third locking member 113 is connected to the third connecting member 150, and the fourth locking member 114 is connected to the fourth connecting member 160.

[0065] When the first locking member 111, the second locking member 112, the third locking member 113, and the fourth locking member 114 are in the locked state, the base 100 can be more stably fixed. When the first locking member 111, the second locking member 112, the third locking member 113, and the fourth locking member 114 are in the unlocked state, the position of the base 100 can be adjusted.

[0066] It should be noted that the first locking member 111, the second locking member 112, the third locking member 113, and the fourth locking member 114 have the same structural composition and the same connection principle with their corresponding connecting members. The connection between the first locking member 111 and the first connecting member 130 is illustrated below:

[0067] like Figure 1 As shown, in some embodiments, the base 100 further includes a connecting rod 170, and the end of the first connecting member 130 away from the body member 120 is connected to the connecting rod 170 via a fourth fixing member 180. The first connecting member 130 has a hollow structure, and the connecting rod 170 can move inside the first connecting member 130. The first locking member 111 is a caster wheel with a locking function. The caster wheel is connected to the end of the connecting rod 170 away from the first connecting member 130 via a fifth fixing member 190.

[0068] It should be noted that the fifth fixing member 190 can be a pin with a ring and a bolt, the bolt being perpendicular to the ground. By adjusting the fixing depth of the bolt, the height between the connecting rod 170 and the ground can be adjusted. Thus, when the ground is uneven, the height of one side of the base 100 can be adjusted by adjusting the fixing depth of the bolt in the fifth fixing member 190, thereby adjusting the position of the calibration plate 300 indirectly connected to the base 100 to ensure that the calibration plate 300 is in a horizontal state. At the same time, the height of the calibration plate 300 can also be finely adjusted so that the position of the calibration plate 300 can meet the calibration requirements of head-up displays in more different vehicle models, expanding the fixing range of the calibration device. In addition, by disassembling the fourth fixing member 180 and the fifth fixing member 190, the first connecting member 130, the connecting rod 170, and the caster wheel can be disassembled more conveniently. When the calibration device is not needed, the space occupied by the calibration device can be reduced through the above disassembly.

[0069] Combination Figures 1 to 2 As shown, in some embodiments, the support assembly 200 includes a first support member 220 and a second support member 230, which are located on opposite sides of the base 100. One end of the first support member 220 is connected to the base 100, and the other end extends away from the base 100. One end of the second support member 230 is connected to the base 100, and the other end extends away from the base 100. The first support member 220 and the second support member 230 are arranged parallel to each other, and both are perpendicular to the base 100. This arrangement, by providing two parallel first support members 220 and second support members 230, both perpendicular to the base 100, allows for more stable fixation of the calibration plate 300.

[0070] Combination Figures 1 to 2 As shown, in some embodiments, the first support member 220 and the second support member 230 are provided with a plurality of first mounting holes 210 in the extending direction. The first mounting holes 210 on the first support member 220 and the first mounting holes 210 on the second support member 230 correspond one-to-one at the same height. It should be noted that connecting the calibration plate 300 to two first mounting holes 210 located at the same height ensures that the calibration plate 300 is in a horizontal state. By connecting the calibration plate 300 to two first mounting holes 210 at different heights, the height of the calibration plate 300 can be adjusted, thereby enabling the calibration plate 300 to meet the calibration requirements of different vehicle models and improving the applicability of the calibration device.

[0071] In some embodiments, the first support member 220 has a first scale area in its extending direction, the first scale area including multiple first scale lines. The second support member 230 has a second scale area in its extending direction, the second scale area including multiple second scale lines. At the same height, the first scale lines and the second scale lines correspond one-to-one, and each first scale line and each second scale line is respectively provided with a first mounting hole 210. This arrangement allows for more precise adjustment of the position of the calibration plate 300 on the first support member 220 and the second support member 230, that is, more precise adjustment of the height of the calibration plate 300, thereby improving the accuracy of the calibration process. It should be noted that the distance between two adjacent first scale lines can be 0.5 mm, and the distance between two adjacent second scale lines can be 0.5 mm. The distance between the first scale line closest to the base 100 and the first scale line farthest from the base 100 can be 2 to 3 m. The distance between the second scale line closest to the base 100 and the second scale line farthest from the base 100 can be 2 to 3 m. In other words, the height of the calibration plate 300 is adjustable within a range of 2-3 mm, with a height adjustment accuracy of 0.5 mm. It can be understood that the distance between adjacent first scale lines, the distance between adjacent second scale lines, and the height adjustment range can be adjusted according to the vehicle's calibration requirements.

[0072] Combination Figures 1 to 2 As shown, in some embodiments, the calibration device further includes a first connecting plate 400, which extends in a direction perpendicular to the support assembly 200 and is located between the support assembly 200 and the calibration plate 300. The first connecting plate 400 is connected to the calibration plate 300 and is connected to any of the first mounting holes 210 of the support assembly 200 via fasteners. It is understood that the calibration plate 300 can be fixed together with the support assembly 200 using the first connecting plate 400. It should be noted that the first connecting plate 400 can be connected to the first mounting holes 210 on the first support member 220 and the second support member 230 at the same height via bolts, screws, or other fasteners, thereby fixing the calibration plate 300 at a specified height on the support assembly 200. It should be noted that the plane of the first connecting plate 400 is parallel to the plane of the calibration plate 300.

[0073] Combination Figures 1 to 2 As shown, in some embodiments, the calibration device further includes a first adjustment plate 500. The first adjustment plate 500 extends in a plane parallel to the first surface 310 along an extension direction perpendicular to the first connecting plate 400.

[0074] The first adjusting plate 500 is provided with a first sliding groove 510, and the extending direction of the first sliding groove 510 is consistent with the extending direction of the first adjusting plate 500. The calibration plate 300 is provided with at least one second mounting hole, and the first connecting plate 400 is provided with at least one third mounting hole, with the second mounting hole and the third mounting hole corresponding one-to-one.

[0075] The calibration plate 300, the first adjusting plate 500, and the first connecting plate 400 are connected by a first fixing member 360 that passes sequentially through a second mounting hole, a first sliding groove 510, and a third mounting hole corresponding to the second mounting hole. It should be noted that the first sliding groove 510 can limit the movement direction of the calibration plate 300, ensuring that the calibration plate 300 can move along the extension direction of the first connecting plate 400, that is, ensuring that the calibration plate 300 can move in a direction parallel to the support member. When the calibration plate 300 moves to the designated position, the fixing member can be tightened to fix the calibration plate 300 at the designated height. Therefore, based on adjusting the fixed height of the first connecting plate 400 and the support assembly 200 to adjust the height of the calibration plate 300, the height position of the calibration plate 300 can be further adjusted, allowing the calibration device to meet the calibration needs of more vehicle models and broadening its applicability. There can be two first fixing members 360.

[0076] Combination Figures 1 to 3 As shown, in some embodiments, the calibration device further includes a second adjustment plate 600 and a third adjustment plate 700. The calibration plate 300 includes a first side 340 and a second side 350, both of which are perpendicular to the support assembly 200. The first side 340 is away from the base 100, and the second side 350 is close to the base 100.

[0077] One end of the second adjusting plate 600 is connected to the end of the first adjusting plate 500 away from the base 100, and one end of the third adjusting plate 700 is connected to the end of the first adjusting plate 500 near the base 100. The second adjusting plate 600 extends along a first direction, wherein the first direction is perpendicular to the calibration plate 300 and extends from the second surface 320 to the first surface 310. The other end of the second adjusting plate 600 extends along a second direction, wherein the second direction is opposite to the first direction.

[0078] The second adjusting plate 600 is provided with a second sliding groove 610, which extends along the first direction. The third adjusting plate 700 is provided with a third sliding groove 710, which extends along the second direction.

[0079] The second adjusting plate 600 is connected to the first adjusting plate 500 via a second fixing member 620 passing through the second slide groove 610. The surface of the second adjusting plate 600 near the base 100 abuts against the first side 340. The third adjusting plate 700 is connected to the calibration plate 300 via a third fixing member 720 passing through the third slide groove 710. The surface of the third adjusting plate 700 away from the base 100 abuts against the second side 350. It should be noted that the thickness of the calibration plate 300 required for different vehicle models may vary. By setting the second slide groove 610 and the third slide groove 710, and using the second fixing member 620 and the third fixing member 720 to pass through the second slide groove 610 and the third slide groove 710 respectively to fix the calibration plate 300, calibration plates 300 of different thicknesses can be fixed, thereby meeting the needs of fixing calibration plates 300 of different thicknesses, satisfying the calibration requirements of different vehicle models, and increasing the applicability of the calibration device. Meanwhile, the use of the second fixing member 620 and the third fixing member 720 for fixing also improves the convenience and efficiency of assembling or disassembling the calibration plate 300. The lengths of the second slide groove 610 and the third slide groove 710 can be 0mm to 20mm respectively.

[0080] Combination Figures 1 to 2 As shown, in some embodiments, the calibration device further includes a clamping member 800, which is connected to one end of the second adjusting plate 600. The clamping member 800 is rotatable around the connection point between the clamping member 800 and the second connecting plate. The clamping member 800 is used to hold the calibration plate 300, and when the clamping member 800 is in the clamping state, it abuts against the second surface 320. By providing the clamping member 800, the calibration plate 300 can be fixed more stably to prevent it from falling off, thereby ensuring the stability of the calibration device assembly.

[0081] Combination Figures 1 to 2As shown, in some embodiments, the calibration device further includes a level device 900. One end of the level device 900 is connected to the first connecting plate 400, and the other end of the level device 900 extends perpendicularly to the first surface 310 and in a direction away from the first surface 310. It should be noted that the level device 900 is generally connected to the side of the first connecting plate 400 that is perpendicular to the extension direction of the support assembly 200 and close to the base 100. The side of the first connecting plate 400 that is perpendicular to the extension direction of the support assembly 200 and close to the base 100 coincides with the second side 350 of the calibration plate 300. The plane of the first connecting plate 400 and the plane of the calibration plate 300 are parallel to each other. Therefore, by measuring whether the first connecting plate 400 is in a horizontal state, it is also equivalent to measuring whether the calibration plate 300 is in a horizontal state. Understandably, by setting up the level device 900, staff can promptly determine whether the calibration plate 300 is level. If the calibration plate 300 is not level, it can be adjusted in a timely manner to ensure it remains level, thereby meeting calibration requirements. In this embodiment, the level device 900 can be a bubble level, which determines whether the calibration plate 300 is level by observing the position and state of the bubbles in the bubble level.

[0082] In some embodiments, a support member 370 is connected to the side of the first connecting plate 400 near the base 100 and perpendicular to the extending direction of the support assembly 200. The support member 370 extends perpendicular to the first connecting plate 400 in a direction away from the first connecting plate 400. One end of the support member 370 connected to the first connecting plate 400 is connected to the first adjusting plate 500. The level device 900 is located on the side of the support member 370 away from the base 100. It is understood that the support member 370 is used to support the total weight of the calibration plate 300, the level device 900, the first connecting plate 400, the first adjusting plate 500, the second adjusting plate 600, and the third adjusting plate 700, thereby ensuring the stability of the calibration device assembly. It should be noted that the extension length of the support member 370 can be 30mm to 50mm, thereby providing sufficient space for the movement of the second fixing member 620 in the second slide groove 610 and the movement of the third fixing member 720 in the third slide groove 710, ensuring that calibration plates 300 of different thicknesses can be fixed.

[0083] Combination Figures 1 to 2As shown, in some embodiments, the calibration device further includes at least one vertical measuring device 1000. The vertical measuring device 1000 is mounted on the first connecting plate 400 and is used to measure the verticality of the first connecting plate 400. It should be noted that the first connecting plate 400 being in a vertical state means that the direction perpendicular to the extension direction of the first connecting plate 400 is perpendicular to the ground. The vertical measuring device 1000 is generally connected to the side of the first connecting plate 400 that is perpendicular to the extension direction of the support assembly 200 and close to the base 100. This side of the first connecting plate 400, perpendicular to the extension direction of the support assembly 200 and close to the base 100, coincides with the second side 350 of the calibration plate 300. The plane containing the first connecting plate 400 is parallel to the plane containing the calibration plate 300. Therefore, measuring whether the first connecting plate 400 is in a vertical state is equivalent to measuring whether the calibration plate 300 is in a vertical state. This allows staff to adjust the position of the calibration plate 300 in a timely manner based on the measurement results in the vertical position, ensuring that the second side 350 of the calibration plate 300 is parallel to the ground.

[0084] In some embodiments, the calibration device includes two vertical measuring devices 1000, which are respectively connected to both ends of the first connecting plate 400. This allows for more accurate measurement of whether the second side 350 of the calibration plate 300 is parallel to the ground, facilitating timely adjustment of the position of the calibration plate 300.

[0085] In some embodiments, the vertical measuring device can be an angle sensor. The vertical state of the first connecting plate 400 is determined by measuring the angle using the angle sensor. In other embodiments, the vertical measuring device includes a protractor, a plumb bob, and a plumb line. The bottom of the protractor is connected to the side of the first connecting plate 400 that is perpendicular to the extension direction of the support assembly 200 and close to the base 100. The plane of the protractor is parallel to the plane of the first connecting plate 400. The 0-degree mark of the protractor is parallel to the side of the first connecting plate 400 that is perpendicular to the extension direction of the support assembly 200 and close to the base 100. One end of the plumb line is connected to the origin of the protractor, and the other end is connected to the plumb bob. It is understood that the plumb bob is in a naturally hanging state, and when the plumb line coincides with the 90-degree mark of the protractor, it indicates that the first connecting plate 400 is in a vertical state.

[0086] Combination Figures 1 to 2As shown, in some embodiments, the calibration device includes at least one first laser element 1100 and at least one second laser element 1200, with one-to-one correspondence between the first laser element 1100 and the second laser element 1200, and both the first laser element 1100 and the second laser element 1200 are connected to the first connecting plate 400. The first laser element 1100 and the second laser element 1200 are connected and perpendicular to each other. A first light ray emitted by the first laser element 1100 is perpendicular to the first surface 310, and a second light ray emitted by the second laser element 1200 is perpendicular to the first light ray. In some embodiments, the first laser element 1100 and the corresponding second laser element 1200 are located on the side of the first connecting plate 400 parallel to the ground. In some embodiments, the calibration device includes two first laser elements 1100 and two second laser elements 1200, with one-to-one correspondence between the first laser element 1100 and the second laser element 1200. One set of first laser elements 1100 and second laser elements 1200 and another set of first laser elements 1100 and second laser elements 1200 are respectively located on both sides of the first connecting plate 400. It should be noted that the first light emitted by the first laser element 1100 will fall on a designated position, such as a marked position on the vehicle used in the calibration process. When the marked position coincides with the first light, it indicates that the position of the calibration plate 300 meets the calibration requirements. When the marked position does not coincide with the first light, it indicates that the position of the calibration plate 300 does not meet the calibration requirements and needs to be readjusted. The second light emitted by the second laser element 1200 can determine whether the second side 350 of the first connecting plate 400 is in a horizontal state. If it is not in a horizontal state, the calibration plate 300 can be adjusted in time.

[0087] It should be noted that the fasteners in the embodiments of this application can all be pins with rings and bolts, so as to facilitate the assembly or disassembly of the connected components.

[0088] The calibration device provided in this application allows for flexible adjustment of the horizontal position and height of the calibration plate 300. This enables the calibration plate 300, fixed at different positions, to meet the calibration requirements of head-up displays for different vehicle models, thus broadening the applicability of the calibration device and reducing calibration costs. Furthermore, since the various connected components are linked by corresponding fasteners, assembly and disassembly are both convenient. When the calibration device is not needed, disassembling the fasteners allows for better organization of its components, reducing the space occupied by the calibration device.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
