Description

Technical Field

[0001] The utility model relates to the technical field of intelligent vehicle control, in particular to a head-up display system reflector and a head-up display system. Background Art

[0002] Traditional car drivers need to frequently look down at the instrument panel during driving to get real-time information such as vehicle speed and engine speed. When they look down, there is a blind spot in front of the car, which poses potential risks. With the development of smart car driving concepts, the on-board head-up display system (HUD) can eliminate the driver's frequent head-down action. HUD products can project instrument information onto the windshield, combining virtual information with the actual road, providing users with a human-computer interaction method that improves driving safety and driving pleasure. In order to accommodate people's different body heights, the main reflector in the HUD product needs to have an adjustable active flip mechanism. Since the existing main reflector must be active and flippable, there is a certain assembly gap between the main reflector and the middle shell. Therefore, when the vehicle passes through bumpy roads, the main reflector will shake and make abnormal noises, which directly affects the content of the virtual image or causes ghosting due to image shaking, causing the driver to be unable to see the image clearly, affecting the driving experience. In addition, long-term shaking and collision of the main reflector and surrounding components will affect the service life of the product. Utility Model Content

[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Example 1

[0033] The present embodiment provides a head-up display system reflector, which includes: a mounting shell 100, a reflector body 200 and an anti-shake fixing member 300. A first rotating shaft 400 and a second rotating shaft 500 are arranged on both sides of the reflector body 200. A mounting hole 101 and a fixing groove 102 are correspondingly opened on the mounting shell 100. The first rotating shaft 400 is inserted into the mounting hole 101, and the second rotating shaft 500 is located in the fixing groove 102. The anti-shake fixing member 300 is arranged at the opening of the fixing groove 102. An elastic member 600 is arranged on the anti-shake fixing member 300, and the elastic member 600 abuts against the second rotating shaft 500, so that the peripheral wall of the second rotating shaft 500 is in contact with the inner wall of the fixing groove 102 and the side wall of the reflector body 200 is in contact with the mounting shell 100.

[0034] Please refer to Figure 1 and Figure 2As shown, in the present embodiment, the mounting shell 100 forms a fixing function, and the reflector body 200 can be connected to the vehicle. In order to adapt to different models of vehicles and ensure clear imaging of the head-up display system, the reflector body 200 is usually rotatably connected to the mounting shell 100, so that the imaging position can be adjusted by rotating the reflector body 200, so that the imaging is clear and complete. However, in order to realize the rotatable connection between the reflector body 200 and the mounting shell 100, the reflector body 200 is usually provided with a rotating shaft, and is rotatably connected to the mounting shell 100 through the rotating shaft, which will cause a certain assembly gap between the mounting shell 100 and the reflector body 200 and the mounting shell 100. This causes the reflector body 200 to shake, produce abnormal noise, and cause imaging jitter and other problems in some bumpy environments. Especially after the reflector has been used for a period of time, with continuous impact and wear, the shaking and abnormal noise will become more obvious. Please refer to Figure 5 As shown, in order to facilitate the installation and rotation adjustment of the reflector body 200, the two ends of the installation shell 100 are respectively provided with a mounting hole 101 and a fixing groove 102, which are respectively used to fix the first rotating shaft 400 and the second rotating shaft 500 on both sides of the reflector body 200. The fixing groove 102 is set as a U-shaped structure with an upper end opening, so that the second rotating shaft 500 can be placed into the fixing groove 102 through the opening. During installation, the first rotating shaft 400 on the reflector body 200 is first inserted into the mounting hole 101, and then the second rotating shaft 500 is placed into the fixing groove 102 through the opening on the fixing groove 102, and finally the anti-shake fixing member 300 is installed at the opening of the fixing groove 102, so as to fix the second rotating shaft 500. After the installation is completed, it is inevitable that there is a certain assembly gap between the first rotating shaft 400, the second rotating shaft 500 and the installation shell 100, which will cause the reflector body 200 to move left and right and shake. At the same time, there will be a certain assembly gap between the second rotating shaft 500 and the inner wall of the fixing groove 102, which causes the second rotating shaft 500 to move up and down. In this embodiment, by providing an elastic member 600 on the anti-shake fixing member 300, the elastic member 600 is abutted against the second rotating shaft 500, so that the peripheral wall of the second rotating shaft 500 is fitted with the inner wall of the fixing groove 102 and the side wall of the reflector body 200 is fitted with the mounting shell 100. Thereby, the assembly gap between the left and right sides of the reflector body 200 and the mounting shell 100 and the assembly gap between the second rotating shaft 500 and the inner wall of the fixing groove 102 are eliminated, thereby avoiding the shaking of the reflector body 200 in the vertical direction and the left and right directions. The head-up display system reflector provided in this embodiment is convenient for installing the reflector body 200 by opening the fixing groove 102 with an opening on the mounting shell 100, and the operation is convenient. At the same time, an elastic member 600 is disposed on the anti-shake fixing member 300 to reduce or eliminate the installation gap between the reflector body 200 and the installation housing 100 , thereby preventing the reflector body 200 from shaking in the vertical direction or in the horizontal direction.

[0035] Optionally, in some implementations of this embodiment, the elastic member 600 includes a first elastic sheet 601, and the side of the reflector body 200 close to the first rotating shaft 400 has an abutment wall 201, and the first elastic sheet 601 abuts against the end surface of the second rotating shaft 500 so that the abutment wall 201 fits against the mounting shell 100.

[0036] Please refer to Figure 7 As shown, in this embodiment, the side of the reflector body 200 close to the first rotating shaft 400 is set as a stepped structure to form an abutting wall 201 that abuts against the opening of the mounting hole 101. The upper end of the fixing groove 102 is open to facilitate the installation of the second rotating shaft 500. The lower end of the fixing groove 102 is set as an arc structure that fits the peripheral wall of the second rotating shaft 500. The second rotating shaft 500 is clamped at the bottom of the fixing groove 102 and fixed by the anti-shake fixing member 300. The second rotating shaft 500 is clamped between the mounting shell 100 and the anti-shake fixing member 300 to prevent the second rotating shaft 500 from slipping. Please refer to Figure 4 As shown, the anti-shake fixing member 300 is provided with a first elastic sheet 601, which abuts against the end of the second rotating shaft 500, so that the reflector body 200 has a tendency to move toward the first rotating shaft 400, so that the abutting wall 201 on the reflector body 200 fits with the mounting housing 100. One end of the reflector body 200 abuts against the hole of the mounting hole 101 through the abutting wall 201, and the other end abuts against the first elastic sheet 601 through the end of the second rotating shaft 500, thereby eliminating the assembly gap between the reflector body 200 and the mounting housing 100 on both sides, and preventing the reflector body 200 from shaking in the left and right directions.

[0037] Optionally, in some implementations of this embodiment, the first elastic sheet 601 is configured as a strip structure, one end of the first elastic sheet 601 is connected to the anti-shake fixing member 300, and the other end is inclined in a direction away from the second rotating shaft 500, thereby forming a guiding inclined surface for guiding the first elastic surface to abut against the second rotating shaft 500.

[0038] Optionally, in some implementations of this embodiment, the elastic member 600 includes a second elastic sheet 602 , and the second elastic sheet 602 abuts against the peripheral wall of the second rotating shaft 500 , so that the peripheral wall of the second rotating shaft 500 fits with the inner wall of the fixing groove 102 .

[0039] Please refer to Figure 3 and Fig. 9As shown, in this embodiment, the second rotating shaft 500 is clamped between the fixing groove 102 and the second elastic piece 602, and the second elastic piece 602 abuts against the peripheral wall of the second rotating shaft 500, so that the second rotating shaft 500 fits the inner wall of the fixing groove 102, thereby eliminating the assembly gap between the second rotating shaft 500 and the fixing groove 102, and preventing the second rotating shaft 500 from shaking when moving along the fixing groove 102. Under the action of the first elastic member 600 and the second elastic member 600, the installation gap between the reflector body 200 and the mounting housing 100 is eliminated, and the reflector body 200 is prevented from shaking and making abnormal noises. The first elastic member 600 and the second elastic member 600 are both arranged on the anti-shake fixing member 300, forming a whole with the anti-shake fixing member 300, with a simple structure and easy installation and disassembly.

[0040] Optionally, in some implementations of this embodiment, the first elastic member 600 , the second elastic member 600 and the anti-shake fixing member 300 are integrally formed to ensure the connection strength between the anti-shake fixing member 300 and the first elastic member 600 and the second elastic member 600 .

[0041] Optionally, in some implementations of this embodiment, an annular fixing piece is disposed on the mounting shell 100 , an end of the first rotating shaft 400 extends into the annular fixing piece, and the first rotating shaft 400 is interference fit with the annular fixing piece.

[0042] Please refer to Figure 5 As shown, in this embodiment, the mounting hole 101 is set as a circular hole structure adapted to the peripheral wall of the first rotating shaft 400. Due to processing errors and for ease of installation, there may be an assembly gap between the first rotating shaft 400 and the mounting hole 101. An annular fixing member is provided on one side of the mounting housing 100 close to the mounting hole 101 to assist in fixing the first rotating shaft 400. The annular fixing member is interference-fitted with the peripheral wall of the first rotating shaft 400, thereby limiting the movement of the first rotating shaft 400 while ensuring the free rotation of the first rotating shaft 400, thereby preventing the first rotating shaft 400 from shaking.

[0043] Optionally, in some implementations of this embodiment, the annular fixing member includes at least two arc-shaped elastic arms 103 , which are symmetrically arranged on the mounting shell 100 , and the inner side walls of the arc-shaped elastic arms 103 abut against the peripheral wall of the first rotating shaft 400 .

[0044] Please refer to Figure 6 As shown, in this embodiment, the annular fixing includes two arc-shaped elastic arms, which are symmetrically arranged to form an annular structure. When the first rotating shaft 400 is clamped between the annular elastic arms, the elastic arms are deformed, and under the action of elastic force, the elastic arms are interference-fitted with the peripheral wall of the first rotating shaft 400, thereby preventing the first rotating shaft 400 from shaking.

[0045] Optionally, in some implementations of this embodiment, a plurality of first oil storage grooves 401 are evenly distributed along the circumferential direction on the inner wall of the mounting hole 101 , and the first oil storage grooves 401 are used to contain lubricating oil.

[0046] Please refer to Figure 5 and Figure 6 As shown, in this embodiment, the first rotating shaft 400 is rotatably arranged in the mounting hole 101. In order to ensure the smoothness of the first rotating shaft 400 during rotation and avoid friction between the first rotating shaft 400 and the inner wall of the mounting hole 101, lubricating oil is coated in the mounting hole 101. Since the gap between the first rotating shaft 400 and the mounting hole 101 is small, the first rotating shaft 400 is prevented from shaking. However, it will make it difficult to store lubricating oil between the first rotating shaft 400 and the inner wall of the mounting hole 101, and it needs to be replenished frequently. In order to avoid the need to replenish lubricating oil frequently, a plurality of first oil storage tanks 401 are provided on the inner wall of the installation for storing lubricating oil to ensure the smooth rotation of the first rotating shaft 400.

[0047] Optionally, in some implementations of this embodiment, a second oil storage tank 502 is opened at the end of the second rotating shaft 500, and the second oil storage tank 502 is used to store lubricating oil.

[0048] Please refer to Fig.10 As shown, in this embodiment, the end of the second rotating shaft 500 abuts against the first elastic sheet 601. In order to avoid friction between the second rotating shaft 500 and the first elastic sheet 601 when the second rotating shaft 500 rotates, a second oil storage tank 502 is opened at the end of the second rotating shaft 500 for storing lubricating oil, thereby ensuring that the second rotating shaft 500 rotates smoothly without much wear and tear on the first elastic sheet 601.

[0049] Optionally, in some implementations of the present embodiment, a limiting groove 301 is provided on the anti-shake fixing member 300, and a limiting boss 501 is correspondingly provided on the second rotating shaft 500. The limiting boss 501 is rotatably disposed in the limiting groove 301, and two sides of the limiting boss 501 are clearance-matched with the limiting groove 301.

[0050] Please refer to Figure 4 and Figure 8As shown, in this embodiment, a limiting boss 501 is provided on the second rotating shaft 500, and a limiting groove 301 is provided on the anti-shake fixing member 300. The limiting boss 501 can move left and right along the limiting groove 301. When the limiting boss 501 moves to a certain position, the limiting boss 501 abuts against the inner wall of the limiting groove 301, thereby limiting the movement of the reflector body 200, preventing the reflector body 200 from moving too far, and protecting the reflector body 200. It can be understood that the reflector body 200 is fixed on the mounting housing 100 under the elastic force of the first elastic sheet 601, and the reflector body 200 is elastically connected to the mounting housing 100. To a certain extent, the elastic pre-tightening provided by the first elastic sheet 601 can ensure that the reflector body 200 shakes left and right to produce abnormal noise or cause imaging jitter. However, in extreme environments, when the reflector body 200 is subjected to excessive force, after overcoming the elastic force of the first elastic sheet 601, the reflector body 200 may move, and in severe cases, the first elastic sheet 601 may be deformed too much and damaged. Due to the action of the limiting groove 301 and the limiting boss 501, the movement of the reflector body 200 is restricted, thereby protecting the reflector body 200 and the first elastic sheet 601.

[0051] Optionally, in some implementations of this embodiment, the second elastic sheet 602 has an arc-shaped assembly surface 6011 , and the assembly surface 6011 fits with the outer arm of the second rotating shaft 500 .

[0052] Please refer to Figure 4 As shown, in this embodiment, a side of the second elastic member that abuts against the second rotating shaft 500 is provided with an arc-shaped assembly surface 6011 that matches the shape of the peripheral wall of the second rotating shaft 500. The assembly surface 6011 is set as an arc-shaped structure, which fixes and limits the second rotating shaft 500 without affecting the rotation effect of the second rotating shaft 500, thereby further improving the anti-shake effect.

[0053] Example 2

[0054] This embodiment provides a head-up display system, which includes an information light source and any one of the head-up display system reflectors described above. The light emitted by the information light source is reflected by a reflector body 200 in the head-up display system reflector and then emitted.

[0055] In this embodiment, the head-up display system adopts the head-up display system reflector with anti-shake effect provided in the above embodiment, and the reflector body 200 can be rotated and adjusted according to the use requirements to ensure clear and complete imaging. During use, the reflector body 200 is stably connected and will not shake, ensuring the stability of imaging. Under bumpy rings, the reflector body 200 will not produce abnormal noise due to assembly gap.

[0056] In summary, the embodiment of the utility model provides a head-up display system reflector, which includes: a mounting shell 100, a reflector body 200 and an anti-shake fixing member 300, a first rotating shaft 400 and a second rotating shaft 500 are arranged on both sides of the reflector body 200, a mounting hole 101 and a fixing groove 102 are correspondingly opened on the mounting shell 100, the first rotating shaft 400 is inserted into the mounting hole 101, the second rotating shaft 500 is located in the fixing groove 102, the anti-shake fixing member 300 is arranged at the opening of the fixing groove 102, and an elastic member 600 is arranged on the anti-shake fixing member 300, and the elastic member 600 abuts against the second rotating shaft 500, so that the peripheral wall of the second rotating shaft 500 is in contact with the inner wall of the fixing groove 102 and the side wall of the reflector body 200 is in contact with the mounting shell 100. The head-up display system reflector provided in this embodiment is convenient for installing the reflector body 200 by opening the fixing groove 102 with an opening on the mounting shell 100, and is easy to operate. At the same time, an elastic member 600 is disposed on the anti-shake fixing member 300 to reduce or eliminate the installation gap between the reflector body 200 and the installation housing 100 , thereby preventing the reflector body 200 from shaking in the vertical direction or in the horizontal direction.

[0057] The embodiment of the utility model also provides a head-up display system, which includes an information light source and any of the head-up display system reflectors described above. By adopting the head-up display system reflector with anti-shake effect provided by the above embodiment, during use, the reflector body 200 is stably connected and will not shake, thereby ensuring the stability of imaging.
