[0051] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0052] Figures 1 to 4A test bench according to the present invention is shown, the test bench includes a base frame 110, a mounting frame 120 and at least two telescopic mechanisms 130, the base frame 110 is used to install the HUD 100 to be tested. The mounting frame 120 includes a first end 127 and a second end 128, and the mounting frame 120 is used to install the windshield 101. The telescopic mechanism 130 includes a fixed portion 131 and a telescopic portion 132, the fixed portion 131 is arranged on the base frame 110, the telescopic portion 132 is movably connected to the fixed portion 131 along the height direction D1, and the telescopic portions 132 of at least two telescopic mechanisms 130 are pivotally connected to the first end 127 and the second end 128, respectively.

[0053] According to the test bench of the utility model, by adjusting the height of the telescopic part 132 relative to the fixed part 131, the height can be adjusted at the first end 127 and the second end 128 of the mounting frame 120 respectively, so that the angle of the mounting frame 120 and the windshield 101 on the mounting frame 120 can be adjusted, so that it can be applied to the testing of different HUDs 100, reducing the testing cost of the HUD 100. In addition, by synchronously lifting the first end 127 and the second end 128 of the mounting frame 120, the height of the windshield 101 on the mounting frame 120 can also be adjusted, so that it can be applied to the testing of different HUDs 100, further reducing the testing cost of the HUD 100.

[0054] Reference Figure 1 The bottom frame body 110 can be formed of a profile, and at least the top of the bottom frame body 110 is made of a profile, so as to facilitate the connection between the bottom frame body 110 and the fixing part 131. In other words, the bottom frame body 110 is provided with a top profile 111, and the top profile 111 can be connected to the fixing part 131 by bolts and other components, which is easy to operate and has a low manufacturing cost.

[0055] Depend on Figure 1 and Figure 2 It can be seen that the test bench includes two mounting frames 120 and eight sets of telescopic mechanisms 130. The two mounting frames 120 are spaced apart in a horizontal direction perpendicular to the front-rear direction D2, and the first end 127, the second end 128 and the middle part 129 of the mounting frame 120 are correspondingly provided with telescopic mechanisms 130. Two telescopic mechanisms 130 are also arranged between the two mounting frames 120, so that the two mounting frames 120 can be stably raised and lowered along the height direction D1.

[0056] Further, see Figure 2 The test bench also includes two driving mechanisms 140, which are respectively arranged at the first end 127 and the second end 128 of the mounting frame 120, so that the first end 127 and the second end 128 of the mounting frame 120 can be driven respectively, thereby facilitating the adjustment of the angle and height of the mounting frame 120.

[0057] Optionally, the driving mechanism 140 includes a hand wheel 141 and a screw rod 142, wherein the hand wheel 141 is sleeved on the screw rod 142 and fixed to the screw rod 142. The screw rod 142 is configured to drive the telescopic portion 132 to move relative to the bottom frame body 110 or the fixed portion 131 along the height direction D1 when rotating, so that the height and angle adjustment of the mounting frame body 120 can be achieved by driving the screw rod 142 to rotate by the hand wheel 141.

[0058] Furthermore, the driving mechanism 140 also includes a first connecting beam 143, which is fixed relative to the base frame 110. Specifically, the first connecting beams 143 of the two driving mechanisms 140 are respectively located at the first end 127 and the second end 128 of the mounting frame 120, and the first connecting beam 143 is connected between the fixing parts 131, so that there is a connection between the two fixing parts 131 corresponding to the two mounting frames 120, thereby improving the stability of the fixing parts 131.

[0059] The screw rod 142 extends along the height direction D1, and the upper end of the screw rod 142 is fixed in the height direction D1 relative to the telescopic part 132, and the lower end of the screw rod 142 is passed through the first connecting beam 143 and is threadedly connected to the first connecting beam 143, so that the height of the first end 127 or the second end 128 of the mounting frame 120 relative to the base frame 110 can be adjusted by rotating the screw rod 142 by the hand wheel 141.

[0060] Furthermore, the driving mechanism 140 also includes a second connecting beam 144, which is connected to the telescopic part 132. The upper end of the screw rod 142 extends to the second connecting beam 144 and is rotatably connected to the second connecting beam 144. Therefore, when the handwheel 141 drives the screw rod 142 to rotate, the screw rod 142 is able to lift and lower the second connecting beam 144, so that the two telescopic parts 132 connected to the second connecting beam 144 and located at the same end of the mounting frame 120 are lifted and lowered synchronously, preventing the mounting frame 120 from tilting, and making the windshield 101 more stable during the lifting process.

[0061] like Figure 2 As shown, a single mounting frame 120 is connected to three sets of telescopic mechanisms 130, and two sets of telescopic mechanisms 130 among the eight sets of telescopic mechanisms 130 are located at the first end 127 of the mounting frame 120 and between the two mounting frames 120, and the two telescopic parts 132 of the two sets of telescopic mechanisms 130 between the mounting frames 120 are both connected to the second connecting beam 144, thereby making the first end 127 of the mounting frame 120 more stable.

[0062] Reference Figure 2 and Figure 3The test bench also includes a locking mechanism 150, which is disposed between the mounting frame 120 and the telescopic portion 132, and is used to lock the mounting frame 120 and the telescopic portion 132, so that after the mounting frame 120 is adjusted, the mounting frame 120 can be stabilized relative to the telescopic portion 132, making the installation of the windshield 101 more stable.

[0063] In detail, the locking mechanism 150 includes a locking plate 151 and a fastener 152, wherein the locking plate 151 is connected to the mounting frame 120. The fastener 152 is disposed on the telescopic portion 132, and the fastener 152 is connected to the locking plate 151, so that when the fastener 152 is fastened, the locking plate 151 and the telescopic portion 132 are fixed, so that the mounting frame 120 is fixed. Furthermore, the locking mechanism 150 also includes a rotation shaft 154, which passes through the locking plate 151 and is provided to the telescopic portion 132, so that the mounting frame 120 is pivotally connected relative to the telescopic portion 132.

[0064] Reference Figure 3 The locking plate 151 is provided with an arcuate groove 153, and the fastener 152 is passed through the arcuate groove 153 to the locking plate 151. The arcuate groove 153 extends around the pivot axis of the mounting frame 120 relative to the telescopic portion 132 (i.e., the axis of the rotating shaft 154), so that the mounting frame 120 can be adjusted to pivot relative to the telescopic portion 132 only by loosening the fastener 152 to keep the fastener 152 passing through the locking plate 151, which is convenient for operation. Optionally, the fastener 152 is movably connected to the telescopic part 132 along the height direction D1. The telescopic part 132 is a profile and is provided with a slide groove 133 extending along the height direction D1. The fastener 152 is a bolt. The head of the fastener 152 is arranged in the slide groove 133, so that the fastener 152 is movable relative to the telescopic part 132 along the height direction D1. When the locking plate 151 rotates with the mounting frame 120, the fastener 152 is not easy to interfere with the inner wall of the arc groove 153 and get stuck, so that the mounting frame 120 can pivot relative to the telescopic part 132 more smoothly.

[0065] Reference Figure 1 and Figure 4 The chassis body 110 is provided with a first mounting member 112, which is suitable for mounting the HUD 100, so that the HUD 100 can be mounted on the chassis body 110. In detail, the first mounting member 112 includes a supporting profile 114 and a receiving shell 113, the receiving shell 113 is suitable for mounting the HUD 100, the supporting profile 114 extends along the height direction D1, the upper end of the supporting profile 114 is connected to the receiving shell 113, and the lower end of the supporting profile 114 is connected to the top profile 111 of the chassis body 110, so that the HUD 100 can be easily disassembled and assembled, and is suitable for mounting different models of HUD 100.

[0066] Furthermore, the mounting frame 120 is provided with a second mounting member 123 . The second mounting member 123 includes a supporting protrusion 126 . The supporting protrusion 126 is suitable for abutting against the windshield 101 , so that the windshield 101 can be mounted on the mounting frame 120 .

[0067] Reference Figure 2 The mounting frame 120 includes a mounting beam 121 and a first profile 122. The mounting beam 121 extends along the front-to-back direction D2, and the first profile 122 is disposed on the top of the mounting beam 121. The mounting beam 121 can also be configured as a profile, thereby reducing manufacturing costs and processing difficulties. The mounting frame 120 is provided with three first profiles 122, which are respectively located at the first end 127, the second end 128 and the middle portion 129 of the mounting beam 121 along the front-to-back direction D2.

[0068] Reference Figure 3 The second mounting component 123 also includes a second profile 124 and a support block 125. The support block 125 is connected to the second profile 124. The support protrusion 126 is arranged on the support block 125. The second profile 124 can be connected to the first profile 122 by fasteners 152 such as bolts, so that the second mounting component 123 suitable for installing the windshield 101 can be detachably installed with the mounting frame 120, so as to be suitable for the installation of windshields 101 of different specifications and sizes.

[0069] In addition, optionally, reference Figure 2 The second mounting member 123 may also be disposed on the telescopic portion 132 of the telescopic mechanism 130 between the two mounting frames 120 , and may also support the windshield 101 .
