Description

Technical Field

[0001] The present application relates to the technical field of HUD rotating mirrors, and in particular to a HUD transmission device with adjustable angle. Background Art

[0002] HUD (Head Up Display), also known as the head-up display system, refers to a driver-centric, blind-operated, multi-function instrument panel. The function of HUD is to project important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see important driving information such as speed and navigation without lowering or turning his head.

[0003] Currently, the angle of the HUD rotating mirror cannot be adjusted, which will result in different drivers with different sitting postures being unable to clearly see the content projected by the HUD rotating mirror on the windshield. As a result, the driver will have to lower his head to view the speed and navigation information, which is not conducive to popularization and use. Utility Model Content

[0026] 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. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0027] Reference Figure 1-6A HUD transmission device with adjustable angle includes a frame 1 and a side plate 9. A servo motor 2 is fixedly connected to the inner wall of the frame 1, and a pentagonal column 3 is fixedly connected to the power output shaft of the servo motor 2. A ball screw 4 is inserted into the outer edge of the pentagonal column 3, and a slider 6 is threadedly connected to the outer edge of the ball screw 4. A HUD rotating mirror 7 is fixedly assembled on the top of the slider 6. Four blocks 10 are symmetrically fixedly assembled on the side of the side plate 9 close to the frame 1, and a positioning mechanism 11 is provided on the inner wall of the frame 1.

[0028] See Figure 5 and Figure 6 The positioning mechanism 11 includes a slot 1101 and a circular hole 1102. The slot 1101 is opened on the side of the frame 1 close to the side plate 9, and the circular hole 1102 is opened on the inner wall of the frame 1. The inner wall of the circular hole 1102 is fixedly connected to one end of a spring 1103, and the other end of the spring 1103 is fixedly connected to a sliding rod 1104. The top of the sliding rod 1104 is fixedly connected to an insertion rod 1105, and the outer edge of the sliding rod 1104 is fixedly equipped with a pull plate 1106, so that pulling the pull plate 1106 drives the sliding rod 1104 to move the position of the adjustable insertion rod 1105, and when the pull plate 1106 is released, the sliding rod 1104 can be subjected to the action of the spring 1103 to drive the insertion rod 1105 to return to its original position.

[0029] See Figure 5 and Figure 6 The side wall of the frame 1 is provided with a sliding groove connected to the circular hole 1102, the pull plate 1106 is slidably connected to the inner wall of the sliding groove, the bottom of the card slot 1101 is provided with a through hole connected to the circular hole 1102, the insertion rod 1105 is slidably connected to the inner wall of the through hole, and the sliding rod 1104 is slidably connected to the inner wall of the circular hole 1102, so that the movement of the sliding rod 1104 can drive the insertion rod 1105 to slide on the inner wall of the through hole, and then completely detach from the inner wall of the card slot 1101.

[0030] See Figure 5 and Figure 6 There are four positioning mechanisms 11, and the four positioning mechanisms 11 are symmetrically arranged on both sides of the frame 1. The four card blocks 10 are arranged on the inner walls of the four card slots 1101, and the inner walls of the four card blocks 10 are provided with insertion holes. The four insertion rods 1105 are inserted into the inner walls of the four insertion holes. The outer side of the side panel 9 is in contact with the outer side of the frame 1, so that the four insertion rods 1105 can be used to position the four card blocks 10, ensuring that the side panel 9 can be stably set at the outer position of the frame 1, thereby ensuring the stability of the connection between the side panel 9 and the frame 1, and separating the card block 10 from the inner wall of the card slot 1101 facilitates the removal of the side panel 9 from the outer side of the frame 1, thereby facilitating the removal of the ball screw 4 for its replacement and maintenance.

[0031] See Figure 3The ball screw 4 is provided with a pentagonal hole 5 that matches the shape of the pentagonal column 3 at one end close to the pentagonal column 3. The pentagonal column 3 is inserted into the inner wall of the pentagonal hole 5. The side of the ball screw 4 away from the pentagonal hole 5 is fixedly assembled with a limit rod 8. A limit hole is provided on the side of the side plate 9 close to the block 10. The limit rod 8 is rotatably connected to the inner wall of the limit hole, so that the pentagonal column 3 can be used to cooperate with the pentagonal hole 5 to connect the output end of the servo motor 2 with the ball screw 4, thereby facilitating the transmission of the rotational force to the ball screw 4 to drive the slider 6 and the HUD rotating mirror 7 to move, and facilitating the separation of the ball screw 4 from the servo motor 2. The limit rod 8 can ensure the stability of the ball screw 4 during rotation and ensure that the ball screw 4 does not swing during rotation.

[0032] See Figure 3 Two limit bars 12 are symmetrically fixed on the outer side of the slider 6, and two limit grooves are symmetrically opened on the inner wall of the frame 1. The two limit bars 12 are slidably connected to the inner wall of the limit groove, so that the slider 6 can be limited during movement, ensuring that it can move stably in a parallel state and will not rotate with the force of the ball screw 4.

[0033] Working principle: When using the device, the servo motor 2 can be driven first to drive the pentagonal column 3 to rotate, and then the rotational force can be transmitted to the ball screw 4 to drive the slider 6 and the HUD rotating mirror 7 to move, thereby realizing angle adjustment, so that the user can clearly see the content projected onto the windshield by the HUD rotating mirror 7 when in different sitting postures. At the same time, the pull plate 1106 can be pulled to drive the slide rod 1104 to move, and then the insertion rod 1105 can be adjusted to disengage from the inner wall of the block 10, and then the positioning mechanism 11 can be removed from the outside of the frame 1, and at the same time the limit rod 8 can be disengaged from the inner wall of the limit hole, and then the ball screw 4 can be pulled to disengage from the pentagonal column 3, and the ball screw 4 and the slider 6 can be removed to the outside, thereby facilitating the replacement of the ball screw 4 and avoiding the wear of the extended thread of the ball screw 4 due to long-term use, affecting the connection between the ball screw 4 and the slider 6.

[0034] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
