Description

Technical Field

[0001] This utility model belongs to the field of HUD technology, and in particular relates to a HUD lens mounting structure. Background Technology

[0002] With the development of automotive intelligent technology, head-up display (HUD) systems, as key components for improving driving safety and convenience, have been widely used in various types of vehicles. HUDs project information such as vehicle speed and navigation onto the windshield or a dedicated display lens, allowing drivers to obtain key information without looking down, effectively reducing the risk of driver distraction.

[0003] Among the core components of a HUD, the large concave mirror is a key optical component for achieving accurate information imaging. Its installation stability directly determines the imaging quality of the HUD. The large concave mirror is usually fixed inside the lower shell of the HUD by a mounting component and then assembled into the central control panel along with the HUD as a whole.

[0004] However, when a car travels over bumpy roads, the large concave mirror and its mounting components will be subjected to significant impact forces, which can easily lead to failures such as cracking of the lens mounting base, deformation or breakage of the lens and rear frame pivot, directly causing HUD image shift and blurring, and seriously affecting its performance. Summary of the Invention

[0005] This utility model provides a HUD lens mounting structure, which aims to solve the problem that the lens and mounting components are easily broken and deformed due to excessive impact force in the case of bumpy car rides, resulting in a decrease in HUD imaging quality.

[0006] To achieve the above objectives, this utility model provides a HUD lens mounting structure, including a housing, a concave panel, a reflective concave mirror, an assembly kit, and a shock-absorbing component. The housing has a concave panel, and a reflective concave mirror is provided on one side of the concave panel. Supporting protrusions are integrally formed on the inner sides of both ends of the housing, and each supporting protrusion has a shaft hole in the middle. Transverse cylinders are integrally formed on the left and right sides of the concave panel, and the transverse cylinders are movably connected by inserting into the shaft holes. Each supporting protrusion has an assembly kit, and a shock-absorbing component is provided inside the assembly kit. The bottom of the shock-absorbing component is used to abut against the surface of the transverse cylinder to cushion the concave panel relative to the housing.

[0007] Preferably, the assembly kit includes a spring and a retaining block. A guide groove is provided through the assembly kit, and a retaining block is provided in the guide groove. A spring is provided between the inner wall of the assembly kit and the top of the retaining block. The bottom of the retaining block passes through the guide groove and is mutually abutted and connected to the surface of the transverse cylinder.

[0008] Preferably, the upper part of the clamping block is provided with a hanging ear, which is suspended in the assembly kit.

[0009] Preferably, the assembly kit has an extended pressing surface on both sides, and a through hole on the extended pressing surface. The support protrusion has threaded holes on both sides of the shaft hole, and the through hole is screwed to the threaded hole by a screw.

[0010] Preferably, the supporting protrusion is provided with a positioning post, and the extended pressing surface is provided with a positioning hole, and the positioning post is inserted into the positioning hole.

[0011] The advantages of this utility model over the prior art are:

[0012] This utility model provides a HUD lens mounting structure. By using a clamping block and a transverse circular shaft to clamp each other, the spring force is used to ensure that the concave panel is damped and buffered when the vehicle is bumpy, so that the reflective concave mirror remains relatively stable and will not break or deform, thus ensuring the imaging quality of the HUD.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To achieve the above objectives, this utility model provides a HUD lens mounting structure, as shown in the reference. Figure 1-3 As shown, the device includes a housing 1, a concave panel 2, a reflective concave mirror, an assembly kit 3, and a shock-absorbing component 4. The housing 1 has a concave panel 2, and a reflective concave mirror is provided on one side of the concave panel 2. Both ends of the housing 1 are integrally formed with support protrusions 5, and each support protrusion 5 has a shaft hole 6 in the middle. The left and right sides of the concave panel 2 are integrally formed with transverse cylinders 7, which are movably connected to the shaft holes 6. Each support protrusion 5 is provided with an assembly kit 3, and the assembly kit 3 contains a shock-absorbing component 4. The bottom of the shock-absorbing component 4 is used to abut against the surface of the transverse cylinder to make the concave panel 2 shock-absorbing and buffered relative to the housing 1.

[0022] Traditionally, due to the need for adjustment, the concave panel 2 uses either a clearance fit or an interference fit between the transverse cylinder 7 and the shaft hole 6. This can result in either excessive looseness affecting HUD imaging quality or a tight fit preventing fine-tuning of the concave panel 2, causing the reflecting concave mirror to be fixed and unadjustable. Combined with vehicle bumps, this leads to poor HUD imaging quality, and may even cause the reflecting concave mirror to become fragile or deformed. This embodiment not only allows the transverse cylinder 7 to be movably connected to the shaft hole 6, enabling the concave panel 2 to rotate relative to the housing 1 for fine-tuning, but also incorporates a shock-absorbing component 4 for close contact with the surface of the transverse cylinder. This provides shock absorption and buffering for the concave panel 2 relative to the housing 1, preventing the reflecting concave mirror from becoming fragile or deformed, and ensuring HUD imaging quality.

[0023] Furthermore, the assembly kit 3 includes a spring 8 and a retaining block 9. A guide groove 10 is provided through the assembly kit 3, and a retaining block 9 is provided in the guide groove 10. A spring 8 is provided between the inner wall of the assembly kit 3 and the top of the retaining block 9. The bottom of the retaining block 9 passes through the guide groove 10 and is abutted against the surface of the transverse cylinder 7. A hanging ear 11 is provided on the upper part of the retaining block 9, and the hanging ear 11 is suspended in the assembly kit 3.

[0024] In this embodiment, during vehicle bumps, the transverse cylinder 7 and the shaft hole 6, based on the clearance fit, will still experience loose vibration. The up-and-down vibration will cause the concave mirror to become fragile. The elastic force of the spring 8 acts on the abutment block 9, so that the bottom of the abutment block 9 and the surface of the transverse cylinder 7 are pressed together. The elastic force of the spring 8 can offset the up-and-down vibration force, buffer and reduce the force, and ensure the imaging quality of the HUD.

[0025] Furthermore, both sides of the assembly kit 3 are provided with extended pressure surfaces 12, and through holes 13 are provided on the extended pressure surfaces 12. The support protrusion 5 is provided with threaded holes 14 on both sides of the shaft hole position 6. The through holes 13 are screwed to the threaded holes 14 by screws. The support protrusion 5 is provided with positioning pins 15, and the extended pressure surfaces 12 are provided with positioning holes 16. The positioning pins 15 are inserted into the positioning holes 16 to ensure assembly accuracy.

[0026] During assembly, the concave mirror is glued to the side of the concave panel 2 with optical adhesive. The transverse cylinders 7 on the left and right sides of the concave panel 2 are aligned with the shaft holes 6 of the support protrusions 5 and slowly inserted to achieve a movable connection. The abutment block 9 with the lug 11 is inserted from the guide groove 10 so that the lug 11 is suspended on the assembly kit 3. The spring 8 is inserted into the assembly kit 3 to abut the abutment block 9. At this time, the spring 8 is in a slightly compressed state. The assembled assembly kit 3 is aligned with the positioning post 15 on the support protrusions 5 and inserted into the positioning hole 16 of the extended pressure surface 12. The assembly kit 3 is then fastened with screws so that the bottom of the abutment block 9 is tightly pressed against the surface of the transverse cylinder 7.

[0027] In one optional embodiment, the HUD is installed on a vehicle for real-vehicle testing. The vehicle continuously passes over speed bumps spaced 50cm apart and 8cm high at a speed of 60km / h, as well as a gravel road section with a high degree of bumpiness. Observation using optical imaging detection equipment shows that the concave mirror does not have obvious vibration or displacement, the image is clear and stable, and the vehicle speed, navigation and other information are not blurred or misaligned. After continuous testing for 1000km, the concave mirror mounting base is disassembled and inspected. There is no cracking, the clearance between the transverse cylinder 7 and the shaft hole 6 is not significantly increased, the assembly kit 3 and the support protrusion 5 are firmly connected, and the shock absorption component 4 is not damaged or failed. The stable protection of the HUD lens effectively ensures the imaging quality of the HUD.

[0028] In summary, this utility model provides a HUD lens mounting structure. By using the clamping block 9 to clamp against the transverse circular shaft, the spring force of the spring 8 is used to ensure that the concave panel 2 is damped and buffered when the vehicle is bumpy, so that the reflective concave mirror remains relatively stable and will not break or deform, thus ensuring the imaging quality of the HUD.

[0029] The technical principles of this utility model have been described above with reference to specific embodiments, which are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. Those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the protection scope of this utility model.
