Description

Technical Field

[0001] This utility model relates to the field of head-up display technology, specifically to a curved mirror fixing structure for a head-up display, a head-up display, and a vehicle. Background Technology

[0002] A head-up display (HUD) projects light from an image source onto the windshield of a vehicle using a reflective optical design, allowing the driver to see the image directly without looking down, thus improving driving safety and providing a better driving experience.

[0003] like Figure 1 As shown, in the existing HUD curved mirror hinge fixing structure, the curved mirror hinge in the HUD is assembled into a base, and then fixed in the base by a snap-fit ​​device. The top surface of the snap-fit ​​device that contacts the curved mirror hinge has a certain elasticity, which can apply a certain elastic pressure to the curved mirror hinge to eliminate the gap between the snap-fit ​​device and the curved mirror hinge surface, and reduce or eliminate the vibration of the curved mirror hinge during vehicle operation. However, in order for the snap-fit ​​device to withstand the impact of the curved mirror hinge on the snap-fit ​​device caused by severe bumps during vehicle operation, it is necessary to increase the overall strength and rigidity of the snap-fit ​​device. This will affect the elasticity of the top surface of the snap-fit ​​device, resulting in increased friction between the top surface of the snap-fit ​​device and the part in contact with the curved mirror hinge due to the increased overall strength of the snap-fit ​​device. This can cause the curved mirror hinge to get stuck in the base, thus affecting the normal operation of the curved mirror hinge. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing fixed structure of the curved mirror shaft causes the curved mirror shaft to jam due to the strengthening of the structure, which affects the normal operation of the shaft.

[0005] In a first aspect, the present invention provides a fixing structure for a curved mirror of a head-up display, for fixing the rotating shaft of the curved mirror of the head-up display, comprising: a base; having a side opening and an upper opening, so that one end of the rotating shaft can be placed in the base; a limiting member, which covers the upper opening of the base in a snap-fit ​​manner; the limiting member includes a base plate, snap-fit ​​portions disposed at both ends of the base plate and spring pieces disposed on the base plate; the base plate is provided with an opening, and the portion of the spring piece opposite to the opening extends through the opening into the base in a non-stressed state.

[0006] Furthermore, the snap-fit ​​portion includes a first snap-fit ​​portion and a second snap-fit ​​portion, wherein the first snap-fit ​​portion and the second snap-fit ​​portion respectively snap-fit ​​with the side walls located on both sides of the opening end of the base.

[0007] Furthermore, the first snap-fit ​​portion is provided with an elastic card protruding toward the side wall corresponding to the base, and the side wall corresponding to the base is provided with a first protrusion for snapping with the elastic card.

[0008] Furthermore, the second snap-fit ​​part is provided with a snap-fit ​​groove, and a second protrusion is provided on the side wall corresponding to the base for snapping with the snap-fit ​​groove.

[0009] Furthermore, the spring includes a fixing part and a spring tongue part; the fixing part is connected to one end of the substrate near the first snap-fit ​​part; the spring tongue part, in the unforced state, passes through the opening on the substrate and extends into the base, elastically abutting against the rotating shaft placed in the base.

[0010] Furthermore, a first fixing hole is provided on the side of the substrate near the first snap-fit, and a corresponding second fixing hole is provided on the base, so as to fasten the limiting member to the base with fasteners.

[0011] Furthermore, a through groove is provided at the position where the fixing part of the spring piece is opposite to the first fixing hole of the substrate.

[0012] Furthermore, the substrate is provided with reinforcing ribs in the areas on both sides of the opening.

[0013] In a second aspect, the present invention also provides a head-up display, which includes the head-up display curved mirror fixing structure as described above.

[0014] In a third aspect, the present invention provides a vehicle that includes the head-up display as described above.

[0015] By adopting the above technical solution, the curved mirror fixing structure of the head-up display of this utility model can ensure the overall strength and impact resistance of the limiting component while also ensuring the appropriate elasticity of the spring, thus effectively eliminating the gap between the rotating shaft and the base, appropriately limiting the rotating shaft, and preventing the rotating shaft from vibrating in the base. Furthermore, it avoids the situation where strengthening the overall strength of the limiting component weakens the overall elasticity of the spring, leading to increased friction between the spring and the rotating shaft, causing the rotating shaft to jam in the base and affecting its normal operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 2 As shown, this application embodiment provides a head-up display curved mirror fixing structure 1, which is used to fix the rotating shaft 2 of the head-up display curved mirror. The rotating shaft 2 is connected to the head-up display curved mirror, and the two ends of the rotating shaft 2 are respectively fixed to two head-up display curved mirror fixing structures 1. The angle of the head-up display curved mirror can be adjusted by rotating the rotating shaft 2.

[0028] like Figures 3 to 6 As shown, the head-up display curved mirror fixing structure 1 includes a base 10 and a limiting member 20 connected together. The base 10 is provided with a side opening end 11 and a top opening end 12, so that one end of the rotating shaft 2 can be inserted into the base 10. The limiting member 20 covers the top opening end 12 of the base 10 in a snap-fit ​​manner, thereby limiting the one end of the rotating shaft 2 inserted into the base 10.

[0029] like Figure 7 and Figure 8 As shown, the limiting member 20 includes a base plate 21, snap-fit ​​portions disposed at both ends of the base plate 21, and spring pieces 22 disposed on the base plate 21. An opening 211 is provided on the base plate 21, and the portion of the spring piece 22 opposite to the opening 211 extends through the opening 211 into the base 10 in a non-stressed state. The spring piece 22 has a certain elasticity, and can undergo corresponding elastic deformation under external force, returning to its original state after the external force is removed.

[0030] Furthermore, such as Figure 7 and Figure 8As shown, the latching portion includes a first latching portion 23 and a second latching portion 24. The first latching portion 23, the substrate 21, and the second latching portion 24 form a U-shaped structure. When the limiting member 20 covers the upper opening end 12 of the base 10, the first latching portion 23 and the second latching portion 24 of the limiting member 20 respectively latch with the opposite side walls on both sides of the side opening end 11 of the base 10. The first latching portion 23 is provided with an elastic card 231 protruding towards the corresponding side wall of the base 10, and a first protrusion 13 is provided on the corresponding side wall of the base 10, such as... Figure 4 , Figure 5 and Figure 7 As shown, it is used to engage with the first snap-fit ​​part 23. The second snap-fit ​​part 24 is provided with a snap-fit ​​groove 241, and a second protrusion 14 is provided on the corresponding side wall of the base 10, as shown... Figure 3 , Figure 6 and Figure 8 As shown, it is used to engage with the snap-fit ​​groove 241. By engaging the first snap-fit ​​portion 23 and the second snap-fit ​​portion 24 of the limiting member 20 with the two side walls opposite to the base 10, the limiting member 20 is securely covered on the upper opening end 12 of the base 10.

[0031] For example Figure 7 and Figure 8 As shown, the spring 22 includes a fixing part 221 and a spring tongue 222; the fixing part 221 is connected to one end of the substrate 21 near the first snap-fit ​​part 23; the spring tongue 222, in the unforced state, passes through the opening 211 on the substrate 21 and is located inside the base 10. When the rotating shaft 2 of the head-up display curved mirror is placed in the base 10, the spring tongue 222 extending into the base 10 elastically abuts against the side wall of the rotating shaft 2. The spring tongue 222 is compressed by the side wall of the rotating shaft 2 and undergoes elastic deformation; at the same time, the spring tongue 222 also applies a corresponding force to the rotating shaft 2, limiting the vibration of the end of the rotating shaft 2 within the base 10.

[0032] Furthermore, such as Figure 7 As shown, to improve the strength of the limiting member 20, reinforcing ribs 213 are provided on the base plate 21 in the area on both sides of the opening 211. By providing reinforcing ribs 213 in this area, not only can the overall strength of the limiting member 20 be improved, but the elasticity of the spring 22 is not affected, so that the spring tongue 222 of the spring 22 can press against the rotating shaft 2 with appropriate elastic force, eliminating the gap between the rotating shaft 2 of the curved mirror and the base 10.

[0033] In this embodiment, the limiting member 20 is configured as two relatively independent parts: a base plate 21 and a spring piece 22. The base plate 21 is engaged with the side wall of the base 10 via a first engaging portion 23 and a second engaging portion 24, thereby covering the upper opening 12 of the base 10. This allows the spring tongue 222 of the spring piece 22, which is provided on the base plate 21, to extend through the opening 211 on the base plate 21 into the base 10, thereby pressing and limiting the rotating shaft 2. This design, in which the base plate 21 and the spring piece 22 are relatively independent in structure and function, not only ensures the overall strength and impact resistance of the limiting member 20 by providing reinforcing ribs 213 on the base plate 21, ensuring reliable engagement between the rotating shaft 2 of the curved mirror and the base 10 when the head-up display is subjected to a certain impact, but also ensures that the spring piece 22 has appropriate elasticity, effectively eliminating the gap between the rotating shaft 2 and the base 10, and appropriately limiting the rotating shaft 2. Furthermore, the overall elasticity of the spring 22 will not be weakened due to the increased overall strength of the limiting component 20, which would lead to increased friction between the spring tongue 222 and the rotating shaft 2, causing the rotating shaft 2 to get stuck in the base 10 and affecting the normal operation of the rotating shaft 2.

[0034] In the first latching portion 23 and the second latching portion 24 of the limiting member 20, which are latched and connected to the base 10, the elastic clip 231 of the first latching portion 23 engages with the first protrusion 13 on the side wall of the base 10, such as... Figure 4 , Figure 5 and Figure 7 As shown, it is an easily detachable snap-fit ​​structure; and the snap-fit ​​groove 241 of the second snap-fit ​​part 24 engages with the snap-fit ​​part 14 on the side wall of the base 10, as shown... Figure 3 , Figure 6 and Figure 8 As shown, this is a snap-fit ​​structure that is not easily loosened. To make the connection between the limiting member 20 and the base 10 more secure, as... Figure 6 and Figure 7 As shown, a first fixing hole 212 is provided on the side of the substrate 21 near the first snap-fit ​​portion 23, and a second fixing hole 15 is provided at the corresponding position on the base 10, for fixing the limiting member 20 to the base 10 by fasteners 3, as shown. Figure 2 As shown. In order to install fastener 3, as Figure 7 As shown, a through groove 223 is provided at the position where the fixing part 221 of the spring piece 22 is opposite to the first fixing hole 212 of the substrate 21, so that the fastener 3 (e.g., screw or bolt) can pass through the through groove 223 and be installed into the first fixing hole 212 and the second fixing hole 15 to fasten the limiting member 20 to the base 10 together.

[0035] When fixing and limiting the rotating shaft 2 of the head-up display curved mirror using the head-up display curved mirror fixing structure 1 of this application embodiment, the end of the rotating shaft 2 is first inserted into the base 10 from the upper opening end 12 of the base 10. Then, the limiting member 20 is placed on the upper opening end 12 of the base 10 and pressed down. This causes the first locking portion 23 and the second locking portion 24 located at both ends of the base plate 21 of the limiting member 20 to slide down along the opposite side walls of the side opening end 11 of the base 10. When the base plate 21 of the limiting member 20 is in contact with the upper end surface of the base 10 and covers the upper opening end 12 of the base 10, the first locking portion 23 and the second locking portion 24 of the limiting member 20 are respectively engaged with the first protrusion 13 and the second protrusion 14 provided on the two side walls of the base 10, thereby connecting the limiting member 20 to the base 10. Finally, fastener 3 is installed into the first fixing hole 212 and the second fixing hole 15, securing the limiting member 20 to the base 10. Installation is now complete. At this point, the spring tongue 222 of the limiting member 20's spring piece 22 elastically abuts against the rotating shaft 2 placed in the base 10.

[0036] An embodiment of this application also provides a head-up display (HUD), which includes the HUD curved mirror fixing structure 1 described above, used to fix both ends of the rotating shaft 2 of the HUD curved mirror. The rotating shaft 2 is connected to the HUD curved mirror. The HUD curved mirror fixing structure 1 can both limit the position of the HUD curved mirror and prevent the angle of the HUD curved mirror from changing due to accidental rotation of the rotating shaft 2; and can also adjust the angle of the HUD curved mirror by rotating the rotating shaft 2 when needed.

[0037] Embodiments of this application also provide a vehicle that includes the head-up display as described above.

[0038] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
