DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 to Figure 3 The present embodiment provides an off-road terrain prop, including a Z-shaped climbing slope, which includes a first slope 1, a second slope 2 and an arch bridge 3. The first end of the first slope 1 is an entry end, the first side of the second end of the first slope 1 is connected to the first end of the arch bridge 3, the second end of the arch bridge 3 is connected to the first side of the first end of the second slope 2, and the second end of the second slope 2 is an exit end. The first side of the first slope 1 is higher than the second side of the first slope 1. The first side of the second slope 2 is higher than the second side of the second slope 2.

[0024] Due to the specific shape of the Z-shaped overpass slope, when the vehicle passes over the arch bridge 3, first one of the front wheels is suspended in the air, and then one of the rear wheels is suspended in the air, thereby simulating the situation where one wheel is suspended in the air during actual off-road driving.

[0025] As a possible example, in this embodiment, the length direction of the first slope 1 is parallel to the length direction of the second slope 2, and both are parallel to the axis direction of the arch bridge 3. According to different actual needs, the length directions of the two slopes can also form an angle greater than zero and less than ninety degrees with the axis direction of the arch bridge 3.

[0026] As a possible example, in this embodiment, the first slope 1 is concave between the first side and the second side, and the second slope 2 is concave between the first side and the second side, so that the slope surface of the first slope 1 and the slope surface of the second slope 2 are both concave curved surfaces. It can be understood that the slope surfaces of the first slope 1 and the second slope 2 can also be inclined planes.

[0027] As a possible example, in this embodiment, the first slope 1, the second slope 2 and the arch bridge 3 are all equipped with guardrails 4. The guardrails 4 can play a protective role to prevent the vehicle body from rushing out sideways.

[0028] As a possible example, in this embodiment, the guardrail 4 includes a column, a connecting rod, a sleeve and a bayonet. There are multiple columns, and the connecting rod is fixedly connected to multiple columns at the same time. The lower end of the column is inserted into the sleeve, and the sleeve is fixed on the first slope 1 or the second slope 2 or the arch bridge 3. The sleeve is provided with a first plug hole for the bayonet to pass through, and the column is provided with multiple second plug holes for the bayonet to pass through. The axial positions of the multiple second plug holes on the column are different. By adjusting the height of the column, the bayonet can be inserted into the second plug holes at different positions, so as to achieve the adjustment of the overall height of the guardrail 4 to meet the protection requirements of different vehicle models.

[0029] As a possible example, in this embodiment, the off-road terrain props further include a wading simulation pool 5, an upward slope 6, and a downward slope 7. The upward slope 6 is connected to one end of the wading simulation pool 5, and the downward slope 7 is connected to the other end of the wading simulation pool 5. The vehicle drives upward from the upward slope 6 to the wading simulation pool 5, then performs wading simulation in the wading simulation pool 5, and then drives away from the downward slope 7.

[0030] As a possible example, in this embodiment, a left wheel recess 61 and a right wheel recess 62 are provided on both the upward slope 6 and the downward slope 7. The left wheel recess 61 is for the left wheel to enter, and the right wheel recess 62 is for the right wheel to enter. Along the driving direction of the vehicle, the left wheel recess 61 and the right wheel recess 62 are staggered. By providing the left wheel recess 61 and the right wheel recess 62, the climbing process on a pothole road can be simulated.

[0031] As a possible example, in this embodiment, the wading simulation pool 5 includes a pool body 51, a hydraulic lifting mechanism 52, a platform 53, a fixed pulley block 54, an anti-front slip fixed roller 55, and an anti-rear slip fixed roller 56. The pool body 51 is used to contain test water, the hydraulic lifting mechanism 52 is used to lift the platform 53, and the platform 53 is used to carry vehicles. The fixed pulley block 54 is installed at the bottom of the pool body 51, the anti-front slip fixed pulley is located at the front side of the fixed pulley block 54, and the anti-rear slip fixed pulley is located at the rear side of the fixed pulley block 54. The platform 53 is provided with a hollow structure. After the platform 53 is lowered, the fixed pulley block 54, the anti-front slip fixed roller 55, and the anti-rear slip fixed roller 56 can pass through the hollow structure upward, so that the fixed pulley block 54 carries the wheel, and the anti-front slip fixed roller 55 and the anti-rear slip fixed roller 56 limit the wheel.

[0032] After the vehicle drives from the uphill slope 6 to the parking position of the platform 53, it stops. The hydraulic lifting mechanism 52 lowers the platform 53 into the pool body 51 so that the pool body 51 is submerged above the platform 53. After the fixed pulley block 54, the anti-front slip fixed roller 55 and the anti-rear slip fixed roller 56 pass through the hollow structure upward, the platform 53 no longer descends. At this time, the tire is supported by the fixed pulley block 54. When the tire rotates, the fixed pulley in the fixed pulley block 54 that contacts the tire rotates accordingly. Due to the effect of buoyancy, the vehicle may float and shift. The forward and backward movement range of the vehicle is limited by the limiting effect of the anti-front slip fixed roller 55 and the anti-rear slip fixed roller 56.

[0033] As a possible example, in this embodiment, both left and right edges of the platform 53 are fixed with limit members 57 to prevent the vehicle from hitting the pool body 51. It should be noted that due to the buoyancy, the vehicle may also float and shift laterally. By setting the limit members 57, the lateral movement range of the vehicle can be limited.

[0034] As a possible example, in this embodiment, the stopper 57 includes a vertical rod and an elastic block, the elastic block is fixed on the vertical rod, and the lower end of the vertical rod is fixed on the platform 53. The elastic block is used to elastically contact the vehicle body to avoid collision damage to the vehicle body. Exemplarily, the material of the elastic block can be rubber.

[0035] As a possible example, in this embodiment, a water outlet valve 58 and a parking mark 59 are installed on the pool body 51. The water outlet valve 58 is used to discharge the water in the pool body 51, and the parking mark 59 is used to locate the front wheel position when the vehicle stops.

[0036] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
