Description

Technical Field

[0001] The embodiments of the utility model relate to the automotive field, and in particular to a head-up display and a vehicle. Background Art

[0002] Head-up display (HUD) is a commonly used auxiliary tool in the automotive industry. It can establish a connection with the car and project some relevant driving information of the car onto the front windshield. The driver only needs to look at the windshield in front to know the current driving information of the car, such as the car's speed.

[0003] The head-up display includes a shell, an image generation unit, a lens mechanism and a power mechanism. The light generated by the image generation unit is reflected by the lens and then emitted to the windshield of the car. The lens mechanism includes a bracket and a lens installed on the bracket. The power mechanism drives the bracket to rotate a preset angle to adjust the lens for flipping, so as to adjust the height of the display screen to meet the needs of different users. At the same time, it can also prevent external light from being reflected back through the lens when the head-up display is idle and causing damage to the image generation unit.

[0004] Generally speaking, during the operation of a head-up display, a preset number of step instructions are usually sent to the motor to control the flipping of the lens to the desired working position. However, after long-term use, the head-up display will have parts that wear out, such as the motor that drives the lens mechanism to rotate. The wear of the motor will cause the accuracy of the motor's action angle to decrease with each step, affecting the actual flipping angle of the lens, causing the lens flipping angle to deviate from the preset angle, which is not conducive to the normal use of the head-up display and thus brings inconvenience.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1-4As shown, one embodiment of the present application provides a head-up display 1, comprising a housing 2, a lens mechanism 3, a power mechanism 4, and a calibration mechanism 5. The housing 2 is provided with a receiving cavity 201, in which both the lens mechanism 3 and the power mechanism 4 are received. The power mechanism 4 is connected to the lens mechanism 3 and is used to drive the lens mechanism 3 to rotate.

[0035] Among them, the calibration mechanism 5 includes a driving component 51 and a calibration component 52. The driving component 51 is respectively connected to the calibration component 52 and the shell 2. The driving component 51 is used to drive the calibration component 52 to work when the power mechanism 4 drives the lens mechanism 3 to rotate, so as to calibrate whether the angle of rotation of the lens mechanism 3 driven by the power mechanism 4 is consistent with the preset angle.

[0036] In this way, by setting up the calibration mechanism 5, the driving component 51 drives the calibration component 52 to work when the lens mechanism 3 rotates, so as to reduce the risk of the rotation angle of the lens mechanism 3 deviating from the preset angle due to the wear and tear of the power mechanism 4, thereby playing the role of calibrating the rotation angle of the lens mechanism 3 and being more convenient to use.

[0037] In some embodiments, as Figure 3 As shown, the lens mechanism 3 includes a detachably mounted bracket 31 and a lens 32. The lens 32 is mounted on the bracket 31 and rotates synchronously with the bracket 31. The bracket 31 includes a bracket body 311 and a rotating shaft 312. One end of the rotating shaft 312 is connected to a side end of the bracket body 311, and the other end of the rotating shaft 312 is connected to the housing 2. The lens 32 is mounted on the bracket body 311 and is connected to the power mechanism 4. The power mechanism 4 can drive the bracket body 311 to rotate relative to the housing 2 about the rotating shaft 312 to adjust the position of the lens 32 on the bracket body 311. In this embodiment, the rotating shaft 312 is connected to two opposite side ends of the bracket body 311. The housing 2 is provided with two support bases 202, and both support bases 202 are rotatably connected to the other end of the rotating shaft 312.

[0038] It can be understood that the number of brackets 31 can increase or decrease according to the number of lenses 32. For example, when the number of lenses 32 is two, the number of brackets 31 is two; when the number of lenses 32 is three, the number of brackets 31 is three, and the corresponding number of support seats 202 is at least three.

[0039] In some embodiments, there are two brackets 31 and two lenses 32. Based on the functions of the lenses 32, the two lenses 32 can be divided into a first lens 32a and a second lens (not shown). The two brackets 31 can be correspondingly divided into a first bracket 31a and a second bracket (not shown). The first lens 32a is provided on the first bracket 31a, and the second lens 32 is provided on the second bracket. The two sides of the first bracket 31a are rotatably connected to the housing 2. Of course, the second bracket can be fixedly mounted on the housing 2 or rotatably mounted on the housing 2. The specific configuration can be as needed. During operation, the light generated by the image generation unit 6 is directed toward the second lens 32, and the second lens 32 reflects the light to the first lens 32a. The light reflected by the first lens 32a can be projected onto the windshield, so that the user can receive the light reflected from the windshield and obtain relevant driving information, such as the driving speed of the vehicle.

[0040] In other embodiments, the bracket 31 and the lens 32 are integrally formed to form the lens mechanism 3, that is, the lens mechanism 3 can be made of a blank material for making a lens and processed to simultaneously form the outer shape of the bracket 31. In this case, the bracket 31 can directly serve as the lens 32.

[0041] In some embodiments, as Figure 3-4 As shown, the power mechanism 4 includes a drive motor 41, a worm 42, and a worm gear 43. The drive motor 41 is mounted on the housing 2. The worm 42 is connected to the output end of the drive motor 41. The worm gear 43 is connected to the bracket 31. The worm 42 is connected to the worm gear 43. When the drive motor 41 drives the worm 42 to rotate, the worm 42 drives the worm gear 43 to rotate the bracket 31, thereby adjusting the position of the lens 32. The worm gear 43 and the bracket 31 can be connected by means of a snap-fit ​​connection, a threaded connection, or an adhesive connection, or can be integrally formed by injection molding or other methods. The specific configuration can be selected according to needs. In this embodiment, the worm gear 43 is integrally formed with the frame body 311 of the first bracket 31a, reducing errors caused by assembly between the two and facilitating the drive motor 41 to drive the first bracket 31a to rotate to adjust the position of the first lens 32a.

[0042] In some embodiments, as Figure 3 As shown, the power mechanism 4 also includes a mounting seat 44, which is installed on the shell 2. The drive motor 41 and the worm 42 are both installed on the mounting seat 44. The mounting seat 44 is used to provide support for the worm 42 to prevent the worm 42 from being easily deformed due to being suspended relative to the shell 2 during use.

[0043] It can be understood that in addition to the above-mentioned structure of the drive motor 41, the worm 42 and the worm gear block 43, the power mechanism 4 can also be other structure, as long as it can drive the bracket 31 to rotate. For example, the power mechanism 4 includes a drive motor 41 and multiple connecting rods, and the multiple connecting rods and the drive motor 41 together construct a crank-connecting rod mechanism to drive the bracket 31 to rotate.

[0044] It should be understood that the number of power mechanisms 4 can be increased according to the number of brackets 31. For example, if two power mechanisms 4 are provided, one of the power mechanisms 4 can be used to drive the first bracket 31a to rotate relative to the shell 2, and the other power mechanism 4 is used to drive the second bracket to rotate relative to the shell 2, so as to achieve the positions of the first lens 32a and the second lens 32 respectively adjusted by the two power mechanisms 4, and then adjust the image projected by the head-up display 1.

[0045] In some implementations, the calibration assembly 52 includes a conductive member 521 and a calibration disk 522. The drive assembly 51 is connected to the bracket 31 and the conductive member 521, respectively. The conductive member 521 and the calibration disk 522 are both connected to the housing 2. The calibration disk 522 is configured to electrically connect to the circuit board 7 of the head-up display 1. The calibration disk 522 is provided with a plurality of protrusions 5221 spaced apart along a predetermined direction. The drive assembly 51 is configured to drive the conductive member 521 to rotate when the power mechanism 4 drives the bracket 31 to rotate, so that the conductive member 521 sequentially abuts the plurality of protrusions 5221 along the predetermined direction.

[0046] Understandable, such as Figure 4 As shown, the calibration disk 522 is provided with a plurality of protrusions 5221, and each protrusion 5221 is spaced apart by a pre-set equal angle, such as 1°, 2°, 3°, etc. When the conductive member 521 abuts from one protrusion 5221 to another adjacent protrusion 5221, it indicates that the bracket 31 has rotated through an equal angle. At this time, the conductive member 521 switches from the initial on state to the off state and then to the on state. That is, when the end of the conductive member 521 that abuts against the protrusion 5221 of the calibration disk 522 is between the two protrusions 5221, the conductive member 521 and the calibration disk 522 are disconnected, and when one end of the conductive member 521 abuts against the protrusion 5221 of the calibration disk 522, the conductive member 521 and the calibration disk 522 are connected. Therefore, when the power mechanism 4 drives the mechanism to rotate, the electrical signal will form a level signal with continuously changing high and low levels, and the angle of rotation of the bracket 31 can be known by the change of the level signal.

[0047] In this way, by setting up the calibration mechanism 5, when the bracket 31 rotates, the driving component 51 drives the conductive member 521 to rotate in a preset direction, and the conductive member 521 intermittently contacts the multiple protrusions 5221 on the rotating disk to generate changing high and low levels, so that the rotation angle of the bracket 31 can be obtained based on the obtained level change signal, and then the actual rotation angle of the bracket 31 can be determined. By comparing the actual rotation angle with the angle required to rotate when the bracket 31 is driven to the working position or the non-working position in advance, it can be known whether the bracket 31 has been rotated to the right position, which is conducive to reducing the risk of the rotation angle of the lens 32 deviating from the preset angle due to the wear and tear of the power mechanism 4, and plays a role in calibrating the rotation angle of the bracket 31, which is more convenient to use. In some embodiments, such as Figure 3-4 As shown, the drive assembly 51 includes a toothed block 511, a gear 512 and a mounting rod 513. The toothed block 511 is installed on the bracket 31 and rotates synchronously with the bracket 31. The gear 512 and the conductive member 521 are both installed on the mounting rod 513. The mounting rod 513 is connected to the housing 2. The toothed block 511 is provided with a toothed portion 5111, which is engaged with the gear 512.

[0048] In this way, when the power mechanism 4 drives the bracket 31 to rotate, it will drive the toothed block 511 to rotate synchronously. Since the toothed block 511 is engaged with the gear 512, the toothed block 511 will drive the gear 512 to rotate to drive the conductive member 521 to rotate synchronously. When the conductive member 521 rotates along the axis of the mounting rod 513 in a preset direction, it will contact the multiple protrusions 5221 on the calibration disk 522 in sequence, causing the circuit to be intermittently turned on and forming a level signal with continuously changing high and low levels. That is, under the action of the driving component 51, the conductive member 521 cooperates with the calibration disk 522 to convert the rotation of the bracket 31 into a changing level signal, so that the actual rotation angle of the bracket 31 can be obtained in real time, reducing the risk of the rotation angle of the lens 32 deviating from the preset angle due to the use loss of the power mechanism 4, and playing a role in calibrating the rotation angle of the bracket 31.

[0049] It should be understood that the tooth block 511 can be a complete gear 512 or a block with a tooth portion 5111 , and the specific method can be selected according to needs. In this embodiment, the tooth block 511 is a block with a tooth portion 5111 .

[0050] In some embodiments, as Figure 3-4As shown, the number of teeth on the toothed portion 5111 is greater than the number of teeth on the gear 512. Thus, when the rotating shaft 312 of the bracket 31 drives the toothed block 511 to rotate by angle A, since the number of teeth on the gear 512 is smaller than that on the toothed portion 5111, the rotation angle can be amplified. The angle B rotated by the gear 512 will be greater than the angle rotated by the toothed block 511, and the corresponding amplitude of the rotation of the conductive member 521 along the preset direction will also be amplified, which facilitates more accurate determination of the actual rotation angle of the bracket 31.

[0051] It should be noted that the angle represented by the spacing between two adjacent protrusions 5221 on the calibration disk 522 can be determined in advance through testing and based on actual design requirements. For example, if the rotation shaft 312 of the bracket 31 drives the toothed block 511 to rotate 3°, and the spacing between two adjacent protrusions 5221 on the calibration disk 522 represents an angle of 0.5°, then the conductive member 521 must sequentially abut six protrusions 5221, corresponding to six changes in the electrical level signal. At this point, the conductive needle rotates from abutting the first protrusion 5221 to abutting the seventh protrusion 5221. Similarly, by directly analyzing the changes in the electrical level signal, the actual rotation angle of the bracket 31 can be determined.

[0052] In some embodiments, the mounting rod 513 can be rotatably connected to the housing 2 or fixedly connected to the housing 2, depending on the specific needs. For example, if the mounting rod 513 is rotatably connected to the housing 2, the gear 512 and the conductive member 521 will both rotate synchronously with the mounting rod 513; if the mounting rod 513 is fixedly mounted to the housing 2, the gear 512 and the conductive member 521 will both rotate synchronously with the mounting rod 513.

[0053] In some embodiments, as Figure 4 As shown, the conductive member 521 includes a sleeve portion 5211 and a rocker portion 5212 connected to each other. The sleeve portion 5211 has a sleeve hole that is sleeved on the mounting rod 513, and the rocker portion 5212 has a protrusion 52121 for abutting against the protrusion 5221. At this time, the sleeve portion 5211 is fixedly connected to the gear 512, so that the rotation of the gear 512 drives the sleeve portion 5211 to rotate.

[0054] In some embodiments, as Figure 1 As shown, the head-up display 1 includes an image generation unit 6, which is accommodated in the accommodating cavity 201 and is used to emit light toward the lens 32. It is understood that the image generation unit 6 can adopt different imaging principles, such as TFT-LCD imaging, DLP imaging, LCOS imaging, and LBS-MEMS imaging, and can be selected and configured according to specific needs.

[0055] In some embodiments, as Figure 3-4As shown, the head-up display 1 further includes a circuit board 7, which is housed in the accommodating cavity 201. The circuit board 7 is respectively connected to the power mechanism 4, the calibration disk 522, and the image generation unit 6. It will be appreciated that when the circuit board 7 controls the power mechanism 4 to drive the bracket 31 to rotate, the conductive member 521 rotates relative to the calibration disk 522 in a predetermined direction under the action of the drive assembly 51. The resulting continuously changing level signal is transmitted to the circuit board 7. After data processing, the circuit board 7 determines whether the current rotation angle of the bracket 31 matches the predetermined angle driven by the power mechanism 4. If not, the circuit board controls the power mechanism 4 to continue driving until the predetermined angle is matched.

[0056] The head-up display 1 provided in an embodiment of the present application includes a housing 2, a lens mechanism 3, a power mechanism 4, and a calibration mechanism 5. The housing 2 is provided with a housing cavity 201. The lens mechanism 3 is accommodated in the housing cavity 201 and is rotatably connected to the housing 2. The power mechanism 4 is accommodated in the housing cavity 201 and is connected to the lens mechanism 3. The power mechanism 4 is used to drive the lens mechanism 3 to rotate. The calibration mechanism 5 includes a drive assembly 51 and a calibration assembly 52. ​​The drive assembly 51 is connected to the calibration assembly 52 and the housing 2, respectively. The drive assembly 51 is used to drive the calibration assembly 52 to operate when the power mechanism 4 drives the lens mechanism 3 to rotate. In this way, by providing the calibration mechanism 5, the drive assembly 51 drives the calibration assembly 52 to operate when the lens mechanism 3 rotates, thereby reducing the risk of the rotation angle of the lens mechanism 3 deviating from the preset angle due to wear and tear of the power mechanism 4, thereby calibrating the rotation angle of the lens mechanism 3.

[0057] In addition, the calibration component 52 includes a conductive member 521 and a calibration disk 522. The calibration disk 522 is provided with a plurality of protrusions 5221 spaced apart along a preset direction. When the bracket 31 rotates, the driving component 51 drives the conductive member 521 to rotate along the preset direction, so that the conductive member 521 intermittently contacts the plurality of protrusions 5221 on the rotating disk to generate changing high and low levels, so that the rotation angle of the bracket 31 can be obtained based on the obtained level change signal, and then the actual rotation angle of the bracket 31 can be determined.

[0058] Another embodiment of the present application provides a vehicle, including the head-up display 1 of the above embodiment. The vehicle includes but is not limited to cars, buses, helicopters, electric vehicles, etc., as long as the head-up display 1 can be installed to display relevant driving information on the windshield.

Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
