[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] In order to ensure that the screen and other components of the head-up display are not damaged and to accurately measure the pressure, this utility model provides a pressure-maintaining fixture for a head-up display in an automobile. The basic concept is to use two pressure sensors placed at both ends of the fixture to measure the pressure. In conjunction with a pressure controller, the pressure threshold is set, and the fixture can be adjusted for curved screens of different sizes and angles. According to a specific embodiment, please refer to Figures 1-4The car head-up display 1 is placed horizontally, and a first clamping block 2 and a second clamping block 3 are symmetrically arranged at both ends of the car head-up display 1. The first clamping block 2 and the second clamping block 3 are respectively provided with a first limiting groove 21 and a second limiting groove 31 facing the two ends of the car head-up display 1. The design of the first limiting groove 21 and the second limiting groove 31 is adapted to the two ends of the car head-up display 1, and a buffer pad 22 is provided in the first limiting groove 21 and the second limiting groove 31 to avoid damage to the car head-up display 1.

[0033] Then, inside the first limiting groove 21 and the second limiting groove 31, a first pressure sensor 4 is provided on one end face of the automobile head-up display 1, and a second pressure sensor 5 is provided on the other end face of the automobile head-up display 1; a first force cylinder 8 and a second force cylinder 9 are provided at both ends of the clamp. In this specific embodiment, the first force cylinder 8 and the second force cylinder 9 are air cylinders or oil cylinders; the first pressure sensor 4 and the second pressure sensor 5 are connected to the pressure controller (not shown in the figure); the process of the pressure sensor transmitting data to the controller mainly involves the following key steps: 1. The first pressure sensor 4 and the second pressure sensor 5 sense the pressure change, which 1. The change is usually captured by a pressure sensitive element. The pressure sensitive element can be a different type of sensor element such as piezoresistive, ceramic, diffused silicon, sapphire or piezoelectric. When these elements are subjected to pressure, they will produce corresponding physical changes, such as changes in resistance, capacitance or inductance. 2. The original signals output by the first pressure sensor 4 and the second pressure sensor 5 are amplified and conditioned by the signal processing unit, and the output signals are converted into digital signals by the analog-to-digital converter (ADC). 3. The first pressure sensor 4 and the second pressure sensor 5 are usually connected to the controller through a specific interface. These interfaces can be wired interfaces, such as RS-48 5. RS-232, CAN bus, etc., or wireless interface such as Bluetooth, Wi-Fi, Zigbee, etc. Wired interface has the advantages of stable transmission and strong anti-interference ability, while wireless interface has the advantages of high flexibility and easy deployment. It follows specific communication protocols during data transmission. Common communication protocols include Modbus, CANopen, PROFIBUS, etc. 4. The controller receives data from the first pressure sensor 4 and the second pressure sensor 5 through its built-in interface circuit and communication module. During the receiving process, the controller will verify and analyze the data to ensure the integrity and accuracy of the data. The received data can be converted into actual pressure values ​​or related parameters after being processed by the algorithm inside the controller. These parameters can be used to monitor the operating status of the system, trigger alarms or perform corresponding control operations, and set pressure thresholds. When the pressure in the fixture exceeds the preset threshold, the data acquisition system should be able to automatically trigger the alarm mechanism to remind the operator to take timely measures, such as stopping the force of the first force cylinder 8 and the second force cylinder 9; during the use of the fixture, the buffer pad 22 does not contact the end of the car head-up display 1 to avoid affecting the accuracy of the data, which helps to improve the accuracy of the test results and production efficiency, and provide strong support for the research and development and production of car head-up displays.

[0034] In a further specific embodiment, the first clamp 2 and the second clamp 3 both form an angle α with the horizontal plane, and the angle α ranges from 0.1° to 5°. This angle setting is for a curved screen, and the angle does not need to be adjusted for the same head-up display. When it comes to different angles, it is necessary to replace the clamps with different α angles. Therefore, the operation is slightly cumbersome.

[0035] According to a specific embodiment, the first clamping block 2 and the second clamping block 3 are respectively provided with a first angle adjustment assembly 6 and a second angle adjustment assembly 7 at opposite ends, and the second angle adjustment assembly 7 has the same structure as the first angle adjustment assembly 6; the first angle adjustment assembly 6 includes an adjustment seat 61 and an adjustment plate 62, and the adjustment seat 61 and the adjustment plate 62 are connected by two bolts 63, and the two bolts 63 are respectively arranged on the upper and lower sides of the adjustment seat 61, and the adjustment plate 62 is connected to the first clamping block 2 through a pad 64, and the ends of the two bolts 63 are connected to the two sides of the adjustment plate 62. The depth of the two bolts 63 is adjusted to make the adjustment plate 62 and the first clamping block 2 produce an inclined angle so as to cooperate with the car head-up display 1.

[0036] In a further specific embodiment, the adjustment plate 62 is arc-shaped, and the adjustment plate 62 is used in conjunction with the first arc-shaped groove 611 of the adjustment seat 61. The arc-shaped design can realize the change of the rotation angle. For example, the lower bolt 63 extends toward the car head-up display 1, and the upper bolt 63 does not move. The center of the arc-shaped adjustment plate 62 uses a long bolt to cooperate with the center hole of the adjustment seat 61. The center hole has the adjustment aperture required by the car head-up display 1 when the adjustment plate 62 is rotated.

[0037] In a further specific embodiment, the adjustment plates 62 on both sides are respectively provided with circular grooves 621, and the ends of the two bolts 63 are provided with spherical heads 631. The circular grooves 621 and the spherical heads 631 are matched and connected to each other, thereby improving the contact stability between the adjustment plates 62 and the bolts 63, avoiding possible slipping and causing damage to the car head-up display 1, and improving the accuracy of the data.

[0038] In a further specific embodiment, a wedge block 65 is provided between the adjustment seat 61 and the adjustment plate 62 on one side. The angle of the wedge block 65 is adjusted to tilt it toward the automobile head-up display 1. The wedge block 65 is more conducive to angle adjustment and avoids tightening the bolt 63. The inclined surface of the wedge block 65 can adjust a larger angle.

[0039] In a further specific embodiment, a second arc groove 651 is provided on the wedge block 65, and the spherical head 631 of the bolt 63 is in contact with the second arc groove 651. The wedge block 65 includes a vertical surface 652 that fits the adjustment seat 61 and an inclined surface 653 that contacts one side of the adjustment plate 62, thereby improving the stability of the automobile head-up display 1.
