Description

Technical Field

[0001] This utility model relates to the field of vehicle head-up display technology, specifically a head-up display device. Background Technology

[0002] The purpose of this invention is to provide a head-up display device to solve the problems that existing vehicle HUD systems typically use plastic parts for the rotating and axial positioning structure of the rotating mirror support. As a result, these problems include vibration and dusting, optical contamination, high friction, abnormal noise during operation, insufficient wear and durability, and weakening of the rotating mirror shaft strength during axial positioning. This invention aims to improve the rotating performance of the rotating mirror, the reliability of axial positioning, and the overall imaging quality. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a head-up display device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a head-up display device, comprising: Display panel, base, pressure plate; The display panel has a rotating shaft on both sides, and the base has a mounting groove on both sides. Each mounting groove on both sides has a bearing. The pressure plate is connected to the base and presses the edge of the bearing. The rotating shafts on both sides are respectively inserted into the bearings on both sides and are interference-fitted with the inner ring of the bearing.

[0005] Main working principle: This head-up display device includes a display panel, a base, and a pressure plate. Bearings are installed in mounting slots on both sides of the base. The bearings, as key components supporting the rotation of the shaft, have their outer rings fitted into the mounting slots, providing a stable support foundation for the entire rotating structure. They are connected to the base via the pressure plate, which applies pressure to the bearings in the mounting slots, firmly securing them. This ensures that the bearings will not loosen or shift during operation, guaranteeing the stability and reliability of the rotating structure. The display panel has shafts on both sides, which are inserted into bearings. The bearings with inserted shafts are then placed on either side of the base. The shafts and the inner rings of the bearings use an interference fit, ensuring a tight connection. When the shaft is subjected to external force, it drives the inner rings of the bearings to rotate, while the outer rings remain relatively stationary, thus achieving stable rotation of the shafts within the bearings.

[0006] When the angle of the head-up display (HUD) panel needs to be adjusted, an external force is applied to the panel, causing the pivots on both sides to rotate within bearings. Due to the low coefficient of rolling friction of the bearings, the pivots experience minimal resistance during rotation, allowing the panel to rotate easily around the pivots and enabling flexible angle adjustment. Once the desired angle is achieved, the external force is removed, and the panel remains stable at that position, allowing the driver to clearly view the information displayed. This structure makes the HUD panel angle adjustment convenient and flexible, while ensuring stability after adjustment, providing a superior user experience for the driver.

[0007] Preferably, the outer periphery of the rotating shaft is provided with an outwardly protruding first interference rib, and when the rotating shaft is inserted into the inner ring of the bearing, the first interference rib and the inner ring of the bearing are tightly pressed together in an interference fit.

[0008] Preferably, the rotating shaft is provided with a retaining plate on its periphery, and the retaining plate is installed in the mounting groove.

[0009] Preferably, one side of the mounting groove is provided with an axial positioning groove, and the periphery of the mounting plate is provided with an axial positioning boss. The axial positioning boss is installed in the axial positioning groove and can rotate within the range of the axial positioning groove.

[0010] Preferably, a floating gap is provided between the base and the bearing sidewall, and the width of the floating gap is not less than 0.5 mm.

[0011] Preferably, the pressure plate has an installation arc surface on the side facing the bearing, and the pressure plate is pressed and fitted with the bearing through the installation arc surface.

[0012] Preferably, the mounting arc surface is provided with a second interference rib that protrudes outward. When the pressure plate presses the bearing, the second interference rib and the outer ring of the bearing are in interference fit.

[0013] Preferably, the pressure plate has fixing holes at positions corresponding to both sides of the bearing, and screws pass through the fixing holes to connect with the base and press the bearing together.

[0014] Preferably, the pressure plate is provided with positioning posts on both sides and the base is provided with positioning holes. When the pressure plate is connected to the base, the positioning posts are inserted into the positioning holes for positioning and engagement.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention features rotating shafts on both sides of the display panel, which engage with bearings in mounting slots on the base, with an interference fit between the shafts and the inner rings of the bearings. This design allows the driver to easily apply external force to the display panel, causing it to rotate around the shafts and enabling flexible angle adjustment. The bearings provide precise guidance and stable support for the shaft rotation. During display panel angle adjustment, the shafts rotate smoothly and steadily within the bearings, avoiding jamming or wobbling, thus achieving precise angle adjustment. Furthermore, once the appropriate angle is reached, the display panel remains stably in that position, preventing easy angle changes due to bumps or vibrations during vehicle operation, ensuring the driver can always clearly see the displayed information.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Example 1 This embodiment discloses a head-up display device, such as... Figures 1-5 As shown, the device includes a display panel 1, a base 2, and a pressure plate 3. Bearings 4 are mounted on both sides of the base 2, each with a mounting groove 20. The bearings 4 are placed within the mounting grooves 20. As a key component supporting the rotation of the rotating shaft 10, the outer ring of the bearing 4 mates with the mounting groove 20, providing a stable support foundation for the entire rotating structure. The bearing 4 is connected to the base 2 via the pressure plate 3, which applies pressure to the bearing 4 within the mounting groove 20, firmly securing it in place. This ensures that the bearing 4 will not loosen or shift during device operation, guaranteeing the stability and reliability of the rotating structure. The display panel 1 has rotating shafts 10 on both sides, which are inserted into the bearings 4. The bearings 4 inserted into the rotating shafts 10 are then inserted into the sides of the base 2. Specifically, the display panel 1 can be a reflector. The inner ring of the rotating shaft 10 and the bearing 4 are fitted with an interference fit. The interference fit makes the rotating shaft 10 and the inner ring of the bearing 4 tightly connected. When the rotating shaft 10 is subjected to an external force, it can drive the inner ring of the bearing 4 to rotate together, while the outer ring of the bearing 4 remains relatively stationary, thereby achieving stable rotation of the rotating shaft 10 within the bearing 4.

[0021] When the angle of the head-up display (HUD) panel 1 needs to be adjusted, an external force is applied to the HUD panel 1, causing the rotating shafts 10 on both sides of the HUD panel 1 to rotate within the bearings 4. Because the bearings 4 have a low coefficient of rolling friction, the rotating shafts 10 experience minimal resistance during rotation, allowing the HUD panel 1 to rotate relatively easily around the shafts 10, thus enabling flexible angle adjustment. Once the desired angle is reached, the external force is stopped, and the HUD panel 1 remains stable at that angle, allowing the driver to clearly view the information reflected on the HUD panel 1. This structure makes the angle adjustment of the HUD panel 1 convenient and flexible, while ensuring stability after adjustment, providing a good user experience for the driver.

[0022] In some optional embodiments, the first interference rib 11 on the periphery of the rotating shaft 10 abuts against the inner ring of the bearing 4 when the rotating shaft 10 is inserted into the inner ring of the bearing 4. The interference rib increases the contact pressure and friction between the rotating shaft 10 and the inner ring of the bearing 4, further enhancing the interference fit effect and making the connection between the rotating shaft 10 and the inner ring of the bearing 4 tighter. During the angle adjustment and use of the display panel 1, it can effectively prevent relative sliding between the rotating shaft 10 and the inner ring of the bearing 4, ensuring the stability and reliability of the rotating structure.

[0023] In some optional embodiments, the mounting bracket 12 surrounding the rotating shaft 10 is installed in the mounting groove 20 of the base 2. The mounting bracket 12 serves to initially position and restrict the axial movement of the rotating shaft 10. When the angle of the display panel 1 is adjusted, the mounting bracket 12 rotates relative to the rotating shaft 10 within the mounting groove 20, while preventing the rotating shaft 10 from moving excessively in the axial direction, ensuring that the rotating shaft 10 rotates within its normal operating range, and maintaining the structural stability of the entire device.

[0024] In some optional embodiments, the axial positioning groove 21 on one side of the mounting groove 20 cooperates with the axial positioning boss 13 on the periphery of the mounting plate 12. The axial positioning boss 13 is installed in the axial positioning groove 21 and can rotate within its range. During the angle adjustment of the display panel 1, the axial positioning boss 13 rotates within the axial positioning groove 21, further precisely limiting the axial movement range of the rotating shaft 10, preventing excessive axial movement of the rotating shaft 10, ensuring the stability and accuracy of the rotation of the rotating shaft 10, and making the angle adjustment of the display panel 1 more precise.

[0025] In some optional embodiments, a floating gap with a width of not less than 0.5 mm is provided between the base 2 and the side wall of the bearing 4. Since the base 2 and other components are mostly made of plastic, they are subject to thermal expansion and contraction. When the temperature changes, the plastic components will expand or contract. The floating gap provides space for this thermal expansion and contraction, avoiding excessive stress between the base 2 and the bearing 4 caused by thermal expansion and contraction, preventing damage to the components due to stress concentration, and ensuring the normal operation and service life of the device under different temperature environments.

[0026] In some optional embodiments, the mounting arc surface 30 of the pressure plate 3 facing the bearing 4 presses against the bearing 4. The shape of the mounting arc surface 30 is adapted to the shape of the outer ring of the bearing 4, which can increase the contact area between the pressure plate 3 and the bearing 4, making the pressure distribution of the pressure plate 3 on the bearing 4 more uniform, thereby improving the pressing effect of the pressure plate 3 on the bearing 4, ensuring that the bearing 4 is firmly installed in the mounting groove 20, and reducing the loosening and vibration of the bearing 4 during operation.

[0027] In some optional embodiments, the second interference rib 31 on the mounting arc surface 30 is in an interference fit with the outer ring of the bearing 4 when the pressure plate 3 presses the bearing 4. The second interference rib 31 increases the friction and connection strength between the pressure plate 3 and the outer ring of the bearing 4, further preventing the bearing 4 from loosening when subjected to external forces or device vibration, improving the stability and reliability of the bearing 4 installation, and ensuring that the entire rotating structure can work normally.

[0028] In some optional embodiments, the pressure plate 3 has fixing holes 32 on both sides of the bearing 4, and screws pass through the fixing holes 32 to connect to the base 2. By tightening the screws, the pressure plate 3 applies pressure to the bearing 4, achieving a clamping fit. This connection method is simple and reliable, and the tightening degree of the screws can be adjusted as needed, thereby precisely controlling the clamping force of the pressure plate 3 on the bearing 4 and ensuring that the bearing 4 is securely installed in the mounting groove 20.

[0029] In some optional embodiments, the positioning posts 33 on both sides of the pressure plate 3 and the positioning holes 22 on the surface of the base 2 are positioned and engaged when the pressure plate 3 and the base 2 are connected. When installing the pressure plate 3, inserting the positioning posts 33 into the positioning holes 22 can quickly and accurately determine the relative position of the pressure plate 3 and the base 2, ensuring that the mounting arc surface 30, fixing holes 32 and other components on the pressure plate 3 accurately correspond to the bearings 4, mounting grooves 20 and other components on the base 2, improving assembly efficiency and assembly accuracy, and ensuring the structural stability and performance reliability of the entire device.

[0030] It is worth noting that the bottom of the display panel 1 is provided with a fixed limiting device, that is, when the display panel 1 is adjusted to a suitable position, the fixed limiting device will engage with the base. However, the fixed limiting device is not the focus of this application, and this application will not elaborate on it.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
