[0034] See the instruction manual Figure 1-4 The vehicle battery mounting frame contour detection device of the present invention comprises a base 1, a first vertical slide 2, a second vertical slide 3, a first support rod 4, a second support rod 5, a first sliding sleeve 6, a second sliding sleeve 7, two first signal transmitter mounting seats 8, two first signal receiver mounting seats 9, two first signal transmitters 10, and two first signal receivers 11, wherein the base 1 is a rectangular telescopic frame structure, having a first telescopic edge 1-1, a second telescopic edge 1-2, a first fixed edge 1-3, and a second fixed edge 1-4, the first vertical slide 2 is slidably mounted on the first fixed edge 1-3, the second vertical slide 3 is slidably mounted on the second fixed edge 1-4, and the first sliding sleeve 6 is slidably mounted on A first vertical slide 2, a second slide sleeve 7 is slidably installed on the second vertical slide 3, a first support rod 4 is horizontally fixed to the first slide sleeve 6, a second support rod 5 is horizontally fixed to the second slide sleeve 7, two first signal transmitter mounting seats 8 are slidably provided on the first support rod 4, and the sliding directions of the two first signal transmitter mounting seats 8 are parallel to the length direction of the first support rod 4, two first signal receiver mounting seats 9 are slidably provided on the second support rod 5, and the sliding directions of the two first signal receiver mounting seats 9 are parallel to the length direction of the second support rod 5, a first signal transmitter 10 is located on the first signal transmitter mounting seat 8, and a first signal receiver 11 is located on the first signal receiver mounting seat 9.

[0035] See the instruction manual Figure 5-8 The vehicle battery mounting frame of the present invention includes an upper frame body 12, a lower frame body 13, a connecting structure 14, a first mounting plate 15, a second mounting plate 16, a third mounting plate 17, and a fourth mounting plate 18. The upper frame body 12 and the lower frame body 13 are both rectangular frame structures. The first mounting plate 15, the second mounting plate 16, the third mounting plate 17, and the fourth mounting plate 18 are respectively arranged at the two ends of the two sides of the upper frame body 12 in the vehicle width direction. The upper frame body 12 and the lower frame body 13 are fixedly connected by the connecting structure 14, and the lower planes of the first mounting plate 15, the second mounting plate 16, the third mounting plate 17, and the fourth mounting plate 18 are abutted against the upper plane of the lower frame body 13.

[0036] The first mounting plate 15, the second mounting plate 16, the third mounting plate 17, and the fourth mounting plate 18 have the same structure, and the first mounting plate 15 is taken as an example for specific description. The first mounting plate 15 is provided with a door-shaped through groove, which includes a first vertical edge 15-1 and a second vertical edge 15-2 located on both sides, and a horizontal edge 15-3 connecting the vertical edges 15-1 and 15-2 from the top, and an arc-shaped groove 15-4 is provided at the middle lower edge of the horizontal edge 15-3.

[0037] There are four connecting structures 14 with the same structure, and a specific description is given by taking the connecting structure 14 matched with the first mounting plate 15 as an example. The lower frame 13 is provided with supporting ears 13-1 at the corresponding positions of the four connecting structures 14, and the connecting structure 14 includes a connecting rod 14-1, a wheel axle 14-2, a limiting head 14-3, and a roller 14-4. One end of the connecting structure 14 is hinged to the supporting ear 13-1 through a rotating shaft, and the other end of the connecting structure 14 is provided with a wheel axle 14-2. One end of the roller 14-4 is rotatably inserted in the wheel axle 14-2, and the other end of the roller 14-4 is fixedly provided with a limiting head 14-3. The lower part of the roller 14-4 is placed in the arc groove 15-4, and the limiting head 14-3 is fixedly connected to the first mounting plate 15 by spot welding or bonding.

[0038] Under normal working conditions of the vehicle, the roller 14-4 will not slide in the horizontal edge 15-3 because the stopper 14-3 is fixedly connected to the first mounting plate 15 and the arc-shaped groove 15-4 positions the roller 14-4. At the same time, because the lower planes of the first mounting plate 15, the second mounting plate 16, the third mounting plate 17, and the fourth mounting plate 18 are in contact with the upper plane of the lower frame 13, the connecting rod 14-1 will not rotate around the wheel shaft 14-2.

[0039] After the vehicle is subjected to a lateral collision force exceeding the threshold, the fixed connection between the limit head 14-3 and the first mounting plate 15 fails, that is, the spot welding or bonding is separated. At this time, the roller 14-4 will slide in the horizontal edge 15-3 until it enters the first vertical edge 15-1 or the second vertical edge 15-2. During the sliding process of the roller 14-4, the lower frame 13 and the battery will slide horizontally away from the side collision part, thereby forming a first-level side collision avoidance. After the roller 14-4 enters the first vertical edge 15-1 or the second vertical edge 15-2, a displacement space is formed between the lower planes of the first mounting plate 15, the second mounting plate 16, the third mounting plate 17, and the fourth mounting plate 18 and the upper plane of the lower frame 13. At this time, the connecting rod 14-1 will rotate around the wheel shaft 14-2, driving the lower frame 13 and the battery further away from the side collision part, thereby forming a second-level side collision avoidance.

[0040] The radius of the arc groove 15-4 is the same as the radius of the roller 14-4, which facilitates the fixing of the roller 14-4. The curvature of the arc groove 15-4 should not be too large, preferably 90°, which facilitates the roller 14-4 to slide out of the arc groove 15-4 during a side collision.

[0041] Except for the arc groove 15-4, the width of the other parts of the gate-shaped through groove is the same as the diameter of the roller 14-4, thereby preventing the roller 14-4 from jumping during movement.

[0042] The vehicle battery mounting frame contour detection device of the present invention is installed as follows:

[0043] Step 1: Adjust the first telescopic side 1-1 and the second telescopic side 1-2 of the base 1 so that the length of the first vertical slide 2 matches the length of the battery mounting frame to be tested;

[0044] Step 2: Adjust the height of the first support rod 4 by sliding the first sliding sleeve 6, so that the two first signal transmitter mounting seats 8 are both located at the bottom of the first vertical side of the door-shaped through groove of the corresponding mounting plate; adjust the height of the second support rod 5 by sliding the second sliding sleeve 7, so that the two first signal receiver mounting seats 9 are both located at the bottom of the first vertical side of the door-shaped through groove of the corresponding mounting plate.

If not, it is determined that the contour of the vehicle battery mounting frame is unqualified. If so, enter step S6.
