[0030] The lamp measuring equipment according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 6As shown, the lamp measuring equipment according to the embodiment of the utility model includes: a base 1, a reference positioning point 21, a plurality of positioning plates 3 and a plurality of fixing mechanisms; the reference positioning point 21 is arranged on the base 1, and the reference positioning point 21 is used to correspond to the installation positioning point on the lamp, and the plurality of positioning plates 3 are arranged on the base 1, and the plurality of positioning plates 3 and the reference positioning point 21 are all located on the same side of the lamp, and after the lamp is installed, the plurality of positioning plates 3 are all in contact with the lamp, and the plurality of fixing mechanisms are respectively arranged around the lamp and above the lamp, and the plurality of fixing mechanisms are all used to fix the lamp, and the fixing mechanisms can select a bolt fixing mechanism 41, a nut fixing mechanism 42, a clamping fixing mechanism 43, and a resisting fixing mechanism according to the structure of the lamp.

[0032] In this embodiment, the positions of multiple fixing mechanisms are set according to the structure of the lamp. During installation, the installation positioning point on the lamp is first aligned with the reference positioning point 21 to determine the reference point so that the lamp is located at the exact installation position. Then, multiple fixing mechanisms are used to connect the lamp. At this time, the lamp is in contact with multiple positioning plates 3, indicating that the lamp is installed in place, and the size of the lamp can be measured. Through multiple fixing mechanisms with different structures, the lamp can be fixed from the front, back, left, right, and top positions of the lamp, avoiding displacement or tilting of the lamp, achieving the stability of the lamp, improving the accuracy of the lamp position, avoiding inaccurate measurement data caused by improper installation or tilt of the lamp, and improving the accuracy of the measurement data.

[0033] There are multiple bolt fixing mechanisms 41 , and the multiple bolt fixing mechanisms 41 are respectively installed on multiple positioning plates 3 .

[0034] The bolt fixing mechanism 41 includes a first base 411 and a first bolt 412. The first base 411 is fixedly connected to the positioning plate 3. A first threaded hole is formed on the first base 411. The first bolt 412 is threadedly connected to the first threaded hole. When fixing the lamp, the first bolt 412 passes through the mounting hole on the lamp and is screwed into the first threaded hole.

[0035] In this embodiment, the bolt fixing mechanism 41 is suitable for a portion of the lamp having a mounting hole. The bolt fixing mechanism 41 is directly installed on the positioning plate 3, avoiding the need to add a bracket for installing the bolt fixing mechanism 41, thereby saving installation space, improving installation convenience, and saving installation time. The position of the positioning plate 3 is set according to the position of the mounting hole on the lamp.

[0036] The nut fixing mechanism 42 and the plurality of positioning plates 3 are located on the same side. There are two nut fixing mechanisms 42 , and the plurality of positioning plates 3 are located between the two nut fixing mechanisms 42 .

[0037] The nut fixing mechanism 42 includes a second base 421 and a nut 422 . The nut 422 is fixed on the second base 421 . The nut 422 is used to connect the second bolt on the lamp.

[0038] In this embodiment, the nut fixing mechanism 42 is suitable for a portion of the lamp having a second bolt, and the lamp is fixed by screwing the bolt into the nut 422 .

[0039] The clamping and fixing mechanism 43 is arranged on the same side of the positioning plate 3, and the clamping and fixing mechanism 43 includes a mounting plate 431, a reference block 432, a clamping block 433, a spring 434 and a pull wire 435; the mounting plate 431 is fixedly mounted on the base 1, the reference block 432 is fixed on the mounting plate 431, the clamping block 433 is pin-connected to the reference block 432, one end of the spring 434 is fixedly connected to the reference block 432, the other end of the spring 434 is fixedly connected to the clamping block 433, one end of the pull wire 435 is fixedly connected to the clamping block 433, and the other end of the pull wire 435 runs through the reference block 432.

[0040] In this embodiment, the clamping and fixing mechanism 43 is suitable for the part with a buckle on the lamp. The clamping and fixing mechanism 43 is used to clamp the buckle to fix the lamp. The clamping block 433 and the reference block 432 are in a normally open state under the action of the spring 434. When the lamp needs to be fixed, the buckle on the lamp is placed between the clamping block 433 and the reference block 432. At this time, the pull wire 435 is pulled to make the clamping block 433 approach the reference block 432. Under the action of the pull wire 435, the spring 434 is compressed, and the clamping block 433 gradually moves closer to the reference block 432 to clamp the buckle.

[0041] In another embodiment, grooves are formed on the opposite surfaces of the clamp block 433 and the reference block 432. When the clamp block 433 and the reference block 432 clamp the buckle, the protrusion at one end of the buckle is embedded in the groove to prevent the buckle from being pulled out from between the clamp block 433 and the reference block 432 to cause the lamp to tilt, thereby improving the clamping stability.

[0042] The other end of the pull wire 435 is connected to a winding mechanism, which includes a mounting seat 436, a connecting rod 437, a handle 438 and a locking pin 439. The connecting rod 437 passes through the mounting seat 436 and is rotatably connected to the mounting seat 436. The handle 438 is provided at one end of the connecting rod 437. The other end of the connecting rod 437 is used to wind the pull wire 435. A positioning hole is formed at one end of the mounting seat 436. The locking pin 439 is movably connected to the connecting rod 437. After the connecting rod 437 rotates to a certain position, the locking pin 439 is inserted into the positioning hole to lock the connecting rod 437.

[0043] In this embodiment, the mounting seat 436 is fixed on the base 1, and the axis of the locking pin 439 is parallel to the axis of the connecting rod 437. The locking pin 439 can move back and forth in a straight line along the axis of the locking pin 439. That is to say, when the connecting rod 437 is rotated, the locking pin 439 does not contact the mounting seat 436. When it is necessary to lock the connecting rod 437, the locking pin 439 is inserted into the positioning hole on the mounting seat 436 to fix the connecting rod 437, prevent the pull wire 435 from loosening, and keep the clamping block 433 and the reference block 432 in a clamped state.

[0044] The abutting and fixing mechanism includes a side abutting mechanism 44 and an upper abutting mechanism 45. The side abutting mechanism 44 is arranged opposite to the positioning plate 3. There are two side abutting mechanisms 44, which are arranged at intervals. There are two upper abutting mechanisms 45, which are arranged at intervals.

[0045] In this embodiment, the supporting and fixing mechanism is suitable for the smooth surface of the lamp. The two side supporting mechanisms 44 are arranged at intervals and cooperate with multiple positioning plates 3 to maintain the stability of the lamp. This avoids the phenomenon that the lamp is unevenly stressed and offset when a single side supporting mechanism 44 supports the lamp. The two upper supporting mechanisms 45 are respectively located above the two ends of the lamp, thereby limiting the height of the two ends of the lamp.

[0046] The side supporting mechanism 44 includes a vertical plate 441 and a top column 442 . The top column 442 is threadedly connected to the vertical plate 441 . The size of the top column 442 protruding from the vertical plate 441 is adjustable so as to support the lamp.

[0047] The upper supporting mechanism 45 includes a column 451, a cover plate 452, a buffer 453, an upper locking portion and a side locking portion; the column 451 is fixed on the base 1, one end of the cover plate 452 is rotatably connected to the column 451, when the cover plate 452 is in a horizontal state, the other end of the column 451 protrudes from the column 451, the buffer 453 is arranged on the lower surface of the other end of the cover plate 452, the side locking portion is used to control the cover plate 452 to be in a vertical state, the upper locking portion is used to control the cover plate 452 to be in a horizontal state, and the buffer 453 is used to support the upper end of the headlight.

[0048] In this embodiment, the side locking portion includes a side plate 455 and a second screw pin 456. The second screw pin 456 penetrates the side plate 455 and is threadedly connected to the side plate 455. A first insertion hole is provided on the side wall of the side plate 455 facing the cover plate 452. When the cover plate 452 is erected, the second screw pin 456 is rotated to insert the second screw pin 456 into the first insertion hole to lock the cover plate 452 in a vertical state. At this time, the lamp can be installed to prevent the cover plate 452 from falling suddenly and damaging the lamp during the installation process. The upper locking portion includes a first screw pin 454. When the cover plate 452 is in a horizontal state, the first screw pin 45 The first screw pin 454 is threadedly connected to the cover plate 452. The upper surface of the column 451 is provided with a second threaded hole. The first screw pin 454 can be screwed into the second threaded hole and threadedly connected to the second threaded hole. The horizontal state of the cover plate 452 is controlled by the first screw pin 454, so that the cover plate 452 exerts a certain downward pressure on the lamp, thereby limiting the upper end of the lamp. The buffer 453 can be a rubber pad or a telescopic structure with a certain tension, which has a buffering effect. While achieving the support of the lamp, it avoids a large squeeze on the lamp, thereby ensuring the integrity of the lamp.

[0049] The multiple positioning plates 3 face the installation surface of the lamp, that is, the connection surface between the lamp and the vehicle body. Therefore, multiple fixing mechanisms are arranged there to increase the fixed position of the lamp and achieve the stability of the lamp. The side supporting mechanism 44 faces the light-emitting surface of the lamp, so this surface does not have a fixed structure. The side supporting mechanism 44 is used to support the angle of the lamp, which further improves the stability of the lamp. The upper supporting mechanism 45 faces the upper surface of the lamp, so the lamp is also fixed by abutting, which solves the defect that the upper surface of the lamp does not have a fixed structure, and also achieves the fixation and support of the lamp.
