[0002] In order to facilitate the display, experience or test of the off-road performance of off-road vehicles (SUVs), automobile off-road performance test props are usually used to simulate the actual off-road process of off-road vehicles. Among them, the hump bridge is the core test module of the automobile off-road performance test props. The hump bridge can simulate the actual off-road process on mountain roads and slopes to demonstrate and test the uphill and downhill capabilities of off-road vehicles. However, the current hump bridge has a relatively single function and can only be used to demonstrate and test the climbing and downhill capabilities of off-road vehicles. It cannot demonstrate and test other capabilities, and needs to be used in combination with other props. For example, the "Multifunctional Hump" disclosed in patent number "202420403873.6" combines the hump bridge with other test props to demonstrate and test more performance, but it undoubtedly increases the floor space.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] This implementation provides a multi-functional hump, such as Figures 1 to 9As shown, the road comprises an uphill and downhill slope 1, a hump bridge 2, and a stepped slope 3. These are arranged sequentially along the vehicle's travel direction, which includes forward and reverse travel. Forward travel involves entering via the uphill and downhill slope 1, passing the hump bridge 2, and exiting via the stepped slope 3. Reverse travel involves entering via the stepped slope 3, passing the hump bridge 2, and exiting via the uphill and downhill slope 1. The side elevation of the hump bridge 2 is visually reminiscent of a mountain peak, and a stairway is located on the stepped slope 3, extending uphill along the slope.

[0039] Testing process:

[0040] ① The off-road vehicle drives up the hump bridge 2 along the uphill slope 1 to test and demonstrate the climbing performance of the off-road vehicle. The off-road vehicle drives down the uphill slope 1 along the hump bridge 2 to test and demonstrate the downhill performance of the off-road vehicle.

[0041] ② The off-road vehicle crosses hump bridge 2 to test and demonstrate its slope-climbing performance.

[0042] ③ The off-road vehicle drives up the hump bridge 2 along the step slope 3 to test and demonstrate the stair climbing performance; the off-road vehicle drives down the step slope 3 along the hump bridge 2 to test and demonstrate the stair descending performance of the off-road vehicle.

[0043] In one embodiment, if Figures 1 to 9 As shown, the hump bridge 2 is hinged at its head to the top of the ramp 1, and its tail is hinged at the top of the step ramp 3. The hinge axes of the hump bridge 2, step ramp 3, and ramp 1 are horizontally arranged and perpendicular to the direction of vehicle travel. The hump bridge 2 can be raised or lowered by a lifting mechanism 29.

[0044] Test process: ④ The lifting mechanism 29 lifts the hump bridge 2 to change the slope of the uphill and downhill slopes 1 and the slope of the hump bridge 2, and to test and demonstrate the uphill and downhill performance and the uphill and downstairs performance of the off-road vehicle at different slopes.

[0045] In one embodiment, if Figures 1 to 9 As shown, the hump bridge 2 includes a left runway 21 and a right runway 22. A left flat-top bridge 23 is provided on the left runway 21, and a right flat-top bridge 24 is provided on the right runway 22. The left flat-top bridge 23 and the right flat-top bridge 24 are staggered in front and back along the direction of vehicle travel, giving the hump bridge 2 a cross-axis function.

[0046] Test process: ⑤ After the off-road vehicle drives onto the hump bridge 2, it slowly drives into the right flat-top bridge 24 and the left flat-top bridge 23. At this time, the adhesion forces on the four tires are completely different. Under the extreme state, a pair of diagonal wheels are stuck, while the other pair of diagonal wheels are completely suspended (technical driving is required at this time to experience the performance of the Land Rover challenging large bumpy terrain). In this case, the performance of the front / rear axle differential lock is the decisive factor for whether the vehicle can pass. By locking the front / rear axle differential through the differential lock, the two half-axles are rigidly connected into a whole, so that the wheels on both sides can obtain the same power. At this time, the vehicle can get out of trouble under the force of the powerful drive.

[0047] In one embodiment, if Figures 1 to 9 As shown, the left runway 21 is equipped with a left lifting mechanism 25 and a left mounting opening. The left lifting mechanism 25 is mounted on the hump bridge 2 below the left runway 21. The left flat-top bridge 23 is mounted on the lifting end of the left lifting mechanism 25. Raising and lowering the lifting end of the left lifting mechanism 25 causes the left flat-top bridge 23 to be raised or lowered, and then extended or retracted from the left mounting opening into the left runway 21. The right runway 22 is equipped with a right lifting mechanism 26 and a right mounting opening. The right lifting mechanism 26 is mounted on the hump bridge 2 below the right runway 22. The right flat-top bridge 24 is mounted on the lifting end of the right lifting mechanism 26. Raising and lowering the lifting end of the right lifting mechanism 26 causes the right flat-top bridge 24 to be raised or lowered, and then extended or retracted from the right mounting opening into the right runway 22. This method of raising and lowering the left and right flat-top bridges 23 and 24 enables the hump bridge 2 to combine the functions of raising and lowering the cross-axle and bumpy roads.

[0048] Testing process:

[0049] ⑤ When the left flat-top bridge 23 and the right flat-top bridge 24 are raised, the cross-axle lifting function is realized. When the off-road vehicle drives into the right flat-top bridge 24 and the left flat-top bridge 23, the performance of the front / rear axle differential lock can be tested. At the same time, by adjusting the height of the left flat-top bridge 23 and the right flat-top bridge 24, the fork speed and driving force test experience can also be experienced at a high or low position.

[0050] ⑥ The left flat-top bridge 23 and the right flat-top bridge 24 are lowered and slightly higher than the left flat-top bridge 23 and the right flat-top bridge 24, so as to simulate a bumpy road. The off-road vehicle drives into the right flat-top bridge 24 and the left flat-top bridge 23 and starts the bumpy experience.

[0051] In one embodiment, Figures 1 to 9As shown, the lifting mechanism 29, the left lifting mechanism 25, and the right lifting mechanism 26 are all scissor-type lifts. The scissor-type lift has a wide lifting range. The existing hump height reduction ratio (height adjustment ratio, from shortest to highest) is generally 1:2, while the hump reduction ratio of the scissor-type lift can be 1:3 or 1:4. The specific scissor-type lift includes a lifting chassis 201, a lifting cylinder 202, a lifting arm 203, and a lifting platform 204, including at least two groups of lifting arms 203, each group including two lifting arms 203, and the two lifting arms 203 are hinged to each other to form an X-shaped structure. In the X-shaped structure, one end of one lifting arm 203 is hinged to the lifting chassis 201, and the other end is slidably connected to the lifting platform 204. One end of the other lifting arm 203 is slidably connected to the lifting chassis 201, and the other end is hinged to the lifting platform 204. Each set of lifting arms 203 is equipped with a lifting cylinder 202, the cylinder body of the lifting cylinder 202 is hinged to the lifting chassis 201, and the piston rod of the lifting cylinder 202 is hinged to one of the lifting arms 203. The piston rod of the lifting cylinder 202 can drive the lifting platform 204 to move up and down by extending and retracting the piston rod.

[0052] In one embodiment, Figures 1 to 9 As shown, the left runway 21 and the right runway 22 are respectively provided with a left pulley block 27 and a right pulley block 28. The left pulley block 27 corresponds to the right flat-top bridge 24 in a position perpendicular to the direction of vehicle travel, while the right pulley block 28 corresponds to the left flat-top bridge 23 in a position perpendicular to the direction of vehicle travel. This allows the hump bridge 2 to combine the functions of a lifting cross-axis, a bumpy road, and a pulley road.

[0053] Test process: ⑦ When the off-road vehicle enters hump bridge 2, you can experience the slippage of one front wheel, one rear wheel, or both the front wheel and the opposite rear wheel simultaneously. This simulates slippery road conditions, such as intersections on snow, mud, and rain. When you want to experience the cross-axle lifting and lowering functions or the bumpy road function, lock the left pulley assembly 27 and the right pulley assembly 28. The left pulley assembly 27 and the right pulley assembly 28 can use roller pulley assemblies or ball pulley assemblies. Roller pulley assemblies are composed of multiple rollers arranged in a matrix. Ball pulley assemblies are composed of multiple ball pulleys arranged in a matrix. Regardless of the driving mode, the left pulley assembly 27 and the right pulley assembly 28 must have a self-locking function.

[0054] In one embodiment, Figures 1 to 9As shown, both the left and right pulley blocks 27 and 28 are ball-wheel modules, i.e., ball-wheel pulley blocks. This ball-wheel module includes a mounting base 205, which is equipped with a locking system and a matrix-arranged ball-wheel assembly. A single ball-wheel assembly includes a ball-wheel seat 206, which is provided with a large ball 207. Within the ball-wheel seat 206, three small balls are provided. These three small balls are used to support the large ball 207, allowing it to rotate and slide 360 ​​degrees, allowing for slipping in snow or rain. The large ball 207 and the small balls are locked by a locking system. The locking system is a strong electromagnetic component. Both the large ball 207 and the small balls are ferromagnetic metal balls. When the strong electromagnetic component is activated, the large ball 207 and the small balls no longer rotate under strong magnetism, thereby achieving locking. The strong electromagnetic component can be installed below the mounting base 205. As a preferred option, an upgrade is carried out on the basis of more guaranteed safety performance. A row of steering wheels 208 can be set on both sides of the mounting frame 205. The steering wheels 208 are perpendicular to the mounting frame 205. When the off-road vehicle passes by, the two rows of steering wheels 208 are respectively located on both sides of a single wheel, which play an anti-collision and anti-slip role, making the driving experience safer.

[0055] In one embodiment, Figures 1 to 9 As shown, the stepped road includes a left stepped road 31 and a right stepped road 32 . The left stepped road 31 corresponds to the left runway 21 , and the right stepped road 32 corresponds to the right runway 22 .

[0056] In one embodiment, Figures 1 to 9 As shown, the uphill and downhill slope 1 includes a left slope 11 and a right slope 12. The left slope 11 corresponds to the position of the left runway 21, and the right slope 12 corresponds to the position of the right runway 22. The left slope 11 and the right slope 12 both include an initial slope section and a final slope end. The two ends of the final slope end are respectively hinged to the initial slope section and the hump bridge 2. A transition plate 13 erected on the initial slope section is hinged on the final slope end to ensure that the car smoothly transitions from the initial slope section to the final slope end.

[0057] In one embodiment, Figures 1 to 9 As shown, both the left slope 11 and the right slope 12 are equipped with slide rails for mounting roller modules or step modules, allowing the up and down slope 1 to also function as a step path or pulley path. Positioning holes are provided on the slide rails, the roller modules, and the step modules. The position of the roller modules or step modules can be adjusted by moving the roller modules or step modules along the slide rails. Bolts or latches are then used to connect the positioning holes on the two modules to achieve positioning of the roller modules or step modules.

[0058] In one embodiment, Figures 1 to 9As shown, the system also includes a mounting chassis 4 for mounting the ramp 1, hump bridge 2, and step ramp 3. This mounting chassis 4 can be a split-type structure, meaning each ramp 1, hump bridge 2, and step ramp 3 corresponds to a corresponding mounting chassis 4. During use, these mounting chassis 4 are hoisted separately and then assembled on-site. Alternatively, the mounting chassis 4 can be a single-piece structure, meaning the ramp 1, hump bridge 2, and step ramp 3 are mounted on a single mounting chassis 4. This single-piece structure eliminates the need for later assembly compared to a split-type structure. The mounting chassis 4 has a load-bearing capacity of approximately 10 tons.

[0059] In one embodiment, Figures 1 to 9 As shown, a fall arrester is installed at the top center of the hump bridge 2. The fall arrester's wire rope is locked to the vehicle's towing hook via a hook. This prevents the vehicle from overturning if it loses its center of gravity while traveling over a steep hump (e.g., ≥45 degrees), thus ensuring safety when navigating steep slopes. The hook lock can be a hydraulically-operated automatic release feature, or a contact-operated electric switch for release.

[0060] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
