The control instruction processing module 33 is connected to the driving module signal to control the action of the driving module. The first inverter 30 is used to power the driving module, and the first inverter 30 is used to connect to the vehicle-mounted low-voltage power supply, and the first inverter 30 is used to convert the vehicle-mounted low-voltage power supply voltage into the first power supply voltage required by the driving module.

The drive module is given an instruction through the control instruction processing module 33, and then the detection module is controlled to move, and the detection module detects the head-up display imaging quality.

[0045] It can be seen from the above description that in the head-up display imaging detection device provided in the specific embodiment of the present application, the first inverter 30 and the second inverter 32 are set to convert the vehicle-mounted low-voltage power supply into two different voltages to respectively power the control instruction processing module 33 and the drive module. Specifically, the voltage is determined according to the requirements of the control instruction processing module 33 and the drive module.

Specifically, the support frame is provided with multiple installation positions for the drive modules, thereby improving the versatility of the head-up display imaging detection equipment.

[0049] The center of mass of the detection assembly formed by the detection module and the drive module is lower than the support frame to prevent the head-up display imaging detection device from tipping over. By setting up the support frame, the staff can avoid holding the head-up display imaging detection device, further improving the convenience of operation and reducing the labor intensity of the staff.

Specifically, the first support frame and the second support frame are connected and locked by a first connecting member. In order to ensure the parallelism of the two, preferably, a plurality of first connecting members are provided. Preferably, two adjacent first connecting members are arranged at equal intervals.

The first translation direction guide rail is provided with two, namely, a first guide rail 23 and a second guide rail 26. The first slide rail platform 39 is slidably connected with the first translation direction guide rail along the first translation direction 51, and the first translation direction driving module drives the first slide rail platform 39 to slide back and forth along the first translation direction 51 to change the position of the detection module in the first translation direction 51. Specifically, the bottom end of the first slide rail platform 39 is placed below the support frame.

[0059] In a specific implementation, the first translation direction driving module may be a telescopic rod, and the telescopic rod is telescopic along the first translation direction 51 .

[0060] In another embodiment, the first translation direction driving module includes a first motor 29 and a first transmission mechanism connected thereto, and the first transmission mechanism is in transmission connection with the first slide rail platform 39 to drive the first slide rail platform 39 to slide back and forth along the first translation direction 51.

During operation, the second translation direction transmission assembly 8 changes the position of the detection module in the second translation direction 52 through the above-mentioned mechanical transmission.

[0066] The second transmission mechanism of the second translation direction transmission assembly 8 is a screw mechanism, including but not limited to a ball screw and a T-type screw. The second slide rail platform 44 is supported by two parallel third guide rails 34 and a fourth guide rail 40 .

[0067] In a specific embodiment, the second transmission mechanism is a second ball screw 35, and the second translation direction transmission assembly 8 is installed on the first slide rail platform 39, wherein the second ball screw 35 is connected to the second motor 38 through a second coupling 36, and the second motor 38 is fixed to the first slide rail platform 39 through a second motor seat 37. The third guide rail 34 and the fourth guide rail 40 are parallel to the axis of the second ball screw 35, and the third guide rail 34 and the fourth guide rail 40 are distributed on both sides of the second ball screw 35.

[0068] During the specific assembly, the sliders of the third guide rail 34, the fourth guide rail 40 and the second ball screw 35 are connected to the second slide rail platform 44. Such a structure limits the rotational movement of the second slide rail platform 44 around its plane normal, thereby improving the repeatability of the head-up display imaging detection equipment.

[0069] The driving module further includes a rotation direction transmission assembly 9, which includes a rotating shaft and a rotation driving module for driving the rotating shaft to rotate. Specifically, the rotation driving module drives the rotating shaft to rotate through the third motor 49.

When the first motor 29 drives the first slide rail platform 39 to move along the first translation direction 51, the drag chain 21 drives the wiring of the first motor 29 to move.

[0074] Specifically, the side of the bottom plate 24 close to the user is provided with an outer decorative plate 41 to improve the overall structural aesthetics. At the same time, adjacent suspension rods 22 can be connected by the outer decorative plate 41.

Specifically, the reducers of the first motor 29, the second motor 38 and the third motor 49 are driven by the drivers 19 that are independently set. The mobile terminal module sends instructions to the control instruction processing module 33, thereby controlling the corresponding motors to drive the first slide rail platform 39, the second slide rail platform 44, and the camera mounting platform 45 to move.

[0076] In a specific embodiment, the driving module further includes a base plate 24 and a suspension rod 22, a first translation direction guide rail is mounted on the base plate 24, a second translation direction guide rail is mounted on the first slide rail platform 39, a rotating shaft is mounted on the second slide rail platform 44 through a bearing module, and a detection module is mounted on a camera mounting platform 45, and the camera mounting platform 45 is designed as an integral whole with the rotating shaft. A plurality of suspension rods 22 are mounted circumferentially of the base plate 24, specifically, four suspension rods 22 are mounted circumferentially of the base plate 24, the bottom ends of the four suspension rods 22 are connected to the base plate 24, the top ends of two suspension rods 22 are connected to the first support frame, and the top ends of the other two suspension rods 22 are connected to the second support frame.

In order to facilitate assembly and disassembly, preferably, the first support frame and the second support frame are provided with mounting holes that cooperate with fasteners, and the suspension rod 22 is easily connected to the bottom plate 24, the first support frame, and the second support frame through the fasteners.

[0078] Specifically, the first motor 29 is fixed to the bottom plate 24 through the first motor seat 28 and supported by the first support member 20. The first guide rail 23 and the second guide rail 26 are parallel to the first ball screw 25 and are installed on the bottom plate 24 on both sides of the first ball screw 25. The first guide rail 23, the second guide rail 26 and the slider of the first ball screw 25 are all connected to the first slide rail platform 39. Such a structure limits the rotational movement of the first slide rail platform 39 around its plane normal, thereby improving the repeatability positioning accuracy of the head-up display imaging detection equipment.

[0079] In order to facilitate position adjustment, preferably, the first support frame and the second support frame are provided with a plurality of mounting holes along the length direction, and the suspension rod 22 is connected to the mounting holes at corresponding positions according to the detection position requirements.

[0080] In a specific embodiment, the present application fixes the first inverter 30 of 12V to 24V on the support plate 31, wherein the support plate 31 can be installed on the bottom plate 24, one end of the first inverter 30 is connected to the vehicle-mounted cigarette lighter, and the other end is connected to the driver 19, and the vehicle-mounted power supply can be used to drive the three motors to work. In specific use, the first motor 29 and the second motor 38 are respectively equipped with electromagnetic mechanical brakes. When the power is cut off, the motor mechanical brakes will lock the motor shafts of the first motor 29 and the second motor 38, and then the first slide platform 39 and the second slide platform 44 will remain in the position before the power is cut off after the power is cut off, preventing the position of the camera 50 from changing and affecting the detection results. Of course, a program can also be set to cut off the power to all motors after the camera mounting platform 45 is adjusted to a good position, effectively saving the power consumption of the vehicle-mounted power supply.

[0081] In the present application, the second inverter 32 for converting 12V to 5V is fixedly connected to the support plate 31 to supply power to a control instruction processing module 33 which is also fixed to the support plate 31. The control instruction processing module 33 includes a processing device for receiving control instructions and an outer shell covering the outside of the processing device. By providing the outer shell, the safety of use is improved.

[0082] Since the driving voltage of the motor and the driving voltage of the control signal processing device are usually different from the voltage of the vehicle-mounted low-voltage power supply, the head-up display imaging detection equipment is equipped with a first inverter 30 to convert the vehicle-mounted voltage into the voltage required by the motor and its mechanical brake, and is equipped with a second inverter 32 to convert the vehicle-mounted low-voltage power supply voltage into the driving voltage of the control instruction processing module 33, thereby improving the convenience of the head-up display imaging detection equipment.

[0083] The mobile terminal module can adjust the moving step value of the first translation direction driving module, the moving step value of the second translation direction driving module, and the rotation step value of the rotation driving module. Specifically, the control program of the mobile terminal module can be installed on a mobile phone, a tablet, or a computer, and connected to the control instruction processing module 33 via Bluetooth. Specifically, the horizontal adjustment corresponds to the movement of the first translation direction 51 of the head-up display imaging detection device, the vertical adjustment corresponds to the movement of the second translation direction 52 of the head-up display imaging detection device, and the rotation adjustment corresponds to the rotation direction 53 of the head-up display imaging detection device.

[0084] like Figure 7 As shown, when in use, click the adjustment button for step adjustment, single point for single adjustment, and long press the button to set it to continuous adjustment, for example, pressing for a preset number of seconds is recognized as a long press.

[0085] When in use, the mobile terminal module has the function of sending forward movement and reverse movement instructions to the first slide rail platform 39 and the second slide rail platform 44, and the function of sending forward rotation and reverse rotation instructions to the rotating shaft. In order to achieve fast adjustment and precise adjustment, the program can select the conditional step value before sending the movement and rotation instructions. Specifically, the mobile terminal module is provided with a coarse adjustment unit and a fine adjustment unit, respectively, and the step length of the adjustment can be selected. Figure 7 As shown, for example, the lateral adjustment and the vertical adjustment correspond to the adjustment in the first translation direction 51 and the second translation direction 52, respectively, and the stepping values ​​thereof can be 0.1mm, 0.5mm, 1mm and 5mm, etc., wherein the stepping value is a single pressing process. The rotation adjustment corresponds to the adjustment in the rotation direction 53, and the stepping value thereof can be 0.1°, 0.5° and 1°, etc., wherein the stepping value is a single pressing process, i.e., pressing once adjusts the angle by one stepping value.

[0086] In the first optional embodiment, specifically, the operation instructions of the mobile terminal module include left movement, right movement, upward movement, downward movement, upward rotation and downward rotation. The detection device can be connected to the mobile terminal module installed with the program developed by the present invention through Bluetooth, and the corresponding adjustment button in the program is clicked to adjust the position of the camera 50 accordingly. Click the "left movement" or "right movement" button on the program, and the first motor 29 drives the first slide platform 39 to move left or right along the first translation direction 51 after the driver 19 receives the driving instruction issued by the control instruction processing module 33, thereby driving the camera 50 to move left or right. Click the "upward movement" or "downward movement" button on the program, and the second motor 38 drives the second slide platform 44 to move upward or downward along the second translation direction 52 after the driver 19 receives the driving instruction issued by the control instruction processing module 33. Click the "upward rotation" or "downward rotation" button on the program, and the third motor 49 drives the camera 50 to rotate upward or downward around the rotation direction 53 after the driver 19 receives the driving instruction issued by the control instruction processing module 33.

[0087] The head-up display imaging detection equipment provided in the present application facilitates the realization of small-batch and multi-scenario vehicle-mounted head-up display imaging detection for mass-produced vehicles, has the characteristics of being easy to carry and simple to operate, and is convenient for popularization and use.
