[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0032] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0033] It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] Please refer to Figure 1 , Figure 2 As shown, an embodiment of the present application provides a reflector assembly 10A, including: a reflector 10 and a reflector bracket 11, the reflector 10 and the reflector bracket 11 are connected by a snap-fit ​​module, and a glue dot area 120 is reserved on the reflector 10 and the reflector bracket 11 so that the reflector 10 and the reflector bracket 11 can also be connected through the glue dot area 120.

[0035] The reflector 10 and the reflector bracket 11 are assembled by means of a snap-fit ​​module, and can also be assembled by gluing. The present application adopts an integrated two-type assembly and fixing combination, so that the reflector assembly 10A has the advantages of convenient snap-fit ​​and disassembly, as well as the advantage of firm gluing installation, and can also adapt to changing market demands, with good flexibility and strong applicability.

[0036] At present, most of the reflector components 10A are provided with buckles 110 on the left and right sides to be installed with the reflector bracket 11. When matching, it is only necessary to first align the buckle position 100 of the reflector component 10A with the buckle 110 of the reflector bracket 11, and then press the buckle position 100 to complete the assembly. However, due to the large number of assembled parts, the tolerance accumulation is large, resulting in a gap in the Z direction or a lack of limit in the Z direction, resulting in the product being unable to be completely fixed, and there is a risk of shaking, abnormal noise, and even lens detachment during vibration tests.

[0037] To solve the above problems, the snap-fit ​​module of the present application includes a snap 110 and a first spring buckle 111 arranged on the reflector bracket 11. The two sides of the reflector 10 along the x direction are connected to the reflector bracket 11 through the snap 110, and the back side of the reflector 10 facing the reflector bracket 11 is connected to the reflector bracket 11 along the z direction through the first spring buckle 111.

[0038] For example, Figure 3 , Figure 4 As shown, along the x direction, two groups of buckles 110 are respectively arranged on both sides of the reflector bracket 11, and one group of buckles 110 includes two buckles 110 along the y direction. That is to say, four buckles 110 are arranged on the reflector bracket 11, and the buckle positions 100 on both sides of the reflector 10 along the x direction are correspondingly engaged through the four buckles 110, thereby completing the engagement between the reflector 10 and the reflector 10 along the x direction. Figure 5 shown.

[0039] Furthermore, after the reflector 10 is connected to the reflector bracket 11 along the x direction by the buckle 110, in order to ensure the assembly accuracy of the reflector 10 and the reflector bracket 11 in the x direction, a limiting boss 112 is also provided on the reflector bracket 11, such as Figure 6 , Figure 7 As shown, the reflector 10 is limited by the limiting bosses 112 on both sides along the x-direction and the reflector bracket 11. The setting of the limiting bosses 112 enables the reflector 10 to be snapped into place with the reflector bracket 11 in the x-direction without deviation.

[0040] On this basis, the back side of the reflector 10 is also connected to the reflector bracket 11 through four snap hooks, for example, Figure 3 As shown, the four spring buckles 100 are located on the inner side of the four buckles 110; the setting of the spring buckles eliminates the assembly gap caused by the tolerance accumulation due to the assembly of multiple parts in the z direction, ensuring that the product will not have a large amplitude of shaking and abnormal noise during the vibration test, and there is no risk of the reflector 10 detaching from the reflector bracket 11.

[0041] And, refer to Figure 8 An interference tz of 0.1 mm to 0.3 mm is formed between the reflector 10 and the first spring buckle 111 along the z direction. Such an interference tz can effectively ensure that the gap between the reflector 10 and the reflector bracket 11 in the z direction is eliminated; when the interference tz is 0.2 mm, the effect of eliminating the gap in the z direction is best.

[0042] In addition, Figure 6 , Fig. 9 As shown, the locking module further includes a second snap buckle 113 disposed on the reflector bracket 11 , and the back side of the reflector 10 facing the reflector bracket 11 is connected to the reflector bracket 11 along the y direction through the second snap buckle 113 .

[0043] Two second spring buckles 113 are also provided at the bottom of the reflector bracket 11 , and the reflector 10 is snap-fitted to the reflector bracket 11 along the y direction through the second spring buckles 113 ; the second spring buckles 113 can eliminate the gap between the reflector 10 and the reflector bracket 11 in the y direction.

[0044] In order to ensure that the gap in the y direction is effectively eliminated, an interference ty of 0.1 mm to 0.3 mm is formed between the reflector 10 and the second spring buckle 113 along the y direction.

[0045] On the other hand, in addition to using the above-mentioned snap-fit ​​method to assemble the reflector 10 and the reflector bracket 11, the present application also uses a glue spotting method to fix the reflector 10 and the reflector bracket 11, so that when the snap-fit ​​method does not meet the assembly requirements, the reflector assembly 10A can be switched to glue spotting fixation.

[0046] Specifically, Fig.10 , Fig.11 The glue dispensing area 120 is formed on a side of the reflector 10 facing the reflector bracket 11 and a side of the reflector bracket 11 facing the reflector 10 , and the engaging module is located outside the glue dispensing area 120 .

[0047] The reflector 10 and the reflector bracket 11 are both provided with a glue spot 120, and the glue spot 120 enables the reflector 10 and the reflector bracket 11 to be bonded by glue. The glue has a certain buffering effect, which can eliminate the assembly gap caused by the cumulative tolerance of the assembly of multiple parts in the z direction, and the contact between the structural parts and the glue can reduce the physical deformation and stress change caused by the direct fixation of the structural parts on the lens, and reduce the impact on the optical effect of the lens.

[0048] When dispensing glue, 3M glue is generally used. If the adhesive area of ​​3M glue is not enough or the pressure holding pressure and pressure holding time are not enough during gluing, the lens may fall off during testing. In order to ensure a good gluing effect and meet design requirements, the gluing area of ​​3M glue needs to be increased, but 3M glue is relatively expensive, which will lead to cost increases.

[0049] Therefore, in order to solve this problem, the glue dispensing area 120 on the reflector 10 is arranged around the circumference of the reflector 10, and the glue dispensing area 120 on the reflector bracket 11 is arranged correspondingly.

[0050] The glue spot area 120 is arranged around the back side of the reflector 10, and the glue spot area 120 of the reflector bracket 11 is adapted to be arranged, so as to ensure that the reflector 10 and the reflector bracket 11 can be firmly bonded without wasting glue materials, thereby ensuring a better cost performance.

[0051] At the same time, the glue dispensing area 120 also needs to avoid positions such as the buckle 110 and the limiting boss 112 to ensure that the reflector 10 and the reflector bracket 11 can also be installed in a snap-on manner.

[0052] In addition, the existing 3M adhesive fixation is basically only suitable for plane mirrors (glass). For transparent PC plastic lenses, it will cause the risk of stray light. Therefore, such lenses are not suitable for 3M adhesive fixation to avoid affecting the optical effect.

[0053] The present application forms sun-brushing in the glue dispensing area 120, and the sun-brushing treatment can eliminate the influence of stray light on optics; and there is no need to modify the mold, and the mold can be switched directly, which saves time and effectively completes the requirements on schedule.

[0054] In summary, the reflector assembly 10A provided in the embodiment of the present application can install the reflector 10 and the reflector bracket 11 by means of clip-on and gluing to suit different occasions; it can also effectively eliminate the assembly gap in the z direction due to the accumulated tolerance caused by the assembly of multiple parts, avoid abnormal noise and shaking during the use of the product, thereby improving product quality, improving user experience, and meeting user needs.

[0055] Please refer to Fig.12 , Fig.13 As shown, an embodiment of the present application further discloses a head-up display device, including a middle shell 20 and a reflector assembly 10A as described in any one of the above items, wherein the reflector assembly 10A is disposed in the middle shell 20 .

[0056] The assembly process does not require pre-installation. It is only necessary to assemble the reflector 10 and the reflector bracket 11 first, then install the entire reflector assembly 10A into the middle shell 20, and tighten the screws 21 to complete the assembly; then adapt other corresponding components to be applied to the head-up display technology.

[0057] The head-up display device includes the same structure and beneficial effects as the reflector assembly 10A in the aforementioned embodiment. The structure and beneficial effects of the reflector assembly 10A have been described in detail in the aforementioned embodiment, and will not be repeated here.

[0058] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
