DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] like Figure 1 As shown, a vehicle climbing over a vertical obstacle test fixture includes a base 10, and mirror-symmetrical panels 11 are fixedly connected to the front and rear sides of the top of the base 10, and movable grooves 12 are opened on the opposite sides of the two panels 11. Sliding rods 13 are fixedly connected to the left and right sides of the movable grooves 12. Sliding blocks 21 are slidably connected to the left and right surfaces of the sliding rods 13 respectively, and a support seat 20 is fixedly connected to the inner side of the sliding block 21, and an obstacle mechanism is arranged on the inner side of the support seat 20 on the same side.

[0025] Preferably, the left and right sides of the base 10 are inclined, so as to facilitate vehicles to pass through the base 10 and drive onto the base 10 .

[0026] Preferably, a group of fixing holes 23 are provided on the outer side of the enclosure 11, a threaded groove 22 is provided on the left side of the sliding block 21, and the inner threads of the outermost fixing holes 23 are connected with fixing bolts 24. When in use, the support seat 20 is slid on the sliding rod 13 through the sliding block 21, so as to adjust the position of the support seat 20 inside the enclosure 11. After the position is adjusted appropriately, the corresponding fixing hole 23 is screwed with the threaded groove 22 through the fixing bolt 24, so as to achieve the effect of adjusting the position of the support seat 20 on the enclosure 11 and fixing it. The position of the obstacle mechanism on the base 10 can be effectively adjusted, and multiple obstacle mechanisms can be set on the base 10 to test the test situation of the vehicle continuously crossing multiple obstacle mechanisms.

[0027] refer to Figure 2-4 A movable groove 30 is opened on the inner side of the support seat 20, and a group of positioning grooves 31 are opened on the left and right sides of the movable groove 30 respectively; the obstacle mechanism includes an obstacle plate 40, and a threaded rod 32 is rotatably connected to the inner side of the rear pair of support seats 20, and the threaded rod 32 is threadedly connected to the obstacle plate 40; the upper and lower sides of the inner side of the front support seat 20 are fixedly connected to the guide rod 34, and the guide rod 34 is slidably connected to the obstacle plate 40.

[0028] Preferably, a motor 33 is fixedly connected to the top of the rear support seat 20, and the output end of the motor 33 is fixedly connected to the threaded rod 32. When in use, the motor 33 is started by an external power supply, and the output end of the motor 33 drives the threaded rod 32 to rotate, thereby driving the barrier plate 40 to move up and down, thereby achieving the effect of adjusting the height of the barrier plate 40, and at the same time, the barrier plate 40 slides along the surface of the guide rod 34, thereby achieving the effect of guiding the barrier plate 40 when moving.

[0029] Although the above mechanism can adjust the height of the barrier plate 40, it is not possible to fix the adjusted barrier plate 40. The barrier plate 40 will be run over by the wheels when in use, and part of the vehicle's gravity will press on the surface of the barrier plate 40, which may cause the barrier plate 40 to be driven downward and the threaded rod 32 to be worn. Therefore, a positioning mechanism is proposed.

[0030] refer to Figure 2 and Figure 5 The positioning mechanism includes positioning blocks 50 respectively fixed at both ends of the barrier plate 40, a through slot 51 is provided on the left side inside the positioning block 50, and movable plug-in blocks 52 are slidably connected to the left and right sides inside the through slot 51.

[0031] Specifically, a driving groove 53 is opened at the top of the through groove 51, and a cylinder 57 is fixedly connected to the top of the driving groove 53, and a driving block 54 is fixedly connected to the output end of the cylinder 57, and a pair of clamping blocks 55 are fixedly connected to the left and right sides of the driving block 54 respectively; a pair of clamping pieces 58 are fixedly connected to the inner side of the insertion block 52, and a connecting rod 56 is rotatably connected to the opposite side of the clamping block 55 through a movable shaft, and the outer end of the connecting rod 56 is rotatably connected to the pair of clamping pieces 58 on the corresponding side through a movable shaft.

[0032] Preferably, the cross-section of the through slot 51 is matched to the side size of the insert block 52 , so as to achieve a guiding effect when the insert block 52 moves.

[0033] When the barrier plate 40 moves to a suitable height, the cylinder 57 is activated by an external power supply, and the output end of the cylinder 57 drives the driving block 54 to move downward, and the driving block 54 drives the connecting rod 56 to flip outward, and the flipped connecting rod 56 will push the two plugging blocks 52 to move outward and insert into a certain positioning groove 31, thereby achieving the effect of fixing the height of the barrier plate 40 and supporting the barrier plate 40. When the barrier plate 40 needs to be adjusted, the output end of the cylinder 57 moves upward to drive the driving block 54 to move upward, thereby driving the connecting rods 56 on both sides to move upward and flip inward at the same time, and the flipped connecting rod 56 drives the plugging blocks 52 on both sides to move inward and disengage from the positioning groove 31, thereby releasing the restriction on the barrier plate 40, and then the rotating threaded rod 32 drives the barrier plate 40 to move up and down to adjust the barrier plate 40.

[0034] The working principle of the utility model is as follows: when the barrier plate 40 moves to a suitable height, the cylinder 57 is activated by an external power supply, the output end of the cylinder 57 drives the driving block 54 to move downward, the driving block 54 drives the connecting rod 56 to flip outward, and the flipped connecting rod 56 will push the two plugging blocks 52 to move outward and insert into a certain positioning groove 31, thereby achieving the effect of fixing the height of the barrier plate 40 and supporting the barrier plate 40. When the barrier plate 40 needs to be adjusted, the output end of the cylinder 57 moves upward to drive the driving block 54 to move upward, thereby driving the connecting rods 56 on both sides to move upward and flip inward at the same time, and the flipped connecting rod 56 drives the plugging blocks 52 on both sides to move inward and disengage from the positioning groove 31, thereby releasing the restriction on the barrier plate 40, and then the barrier plate 40 is driven up and down by the rotating threaded rod 32 to adjust the barrier plate 40.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
