[0026] In order to make the technical means, creation characteristics, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0027] As shown in Figures 1-6 A kind of modular spliced electric vehicle energy consumption test bench, including two slopes 1, the opposite side of two slopes 1 is slidably connected with test bench 2, the upper portion of the inner cavity of test bench 2 is rotatably connected with two test rollers 7, the opposite side of two test bench 2 is slidably connected with support mechanism 3;

[0028] Support mechanism 3 includes two support tables 31, the opposite side of two support tables 31 is slidably connected at the opposite side of two test bench 2, the upper surface of two support tables 31 is slidably connected with support plate 34, the lower surface of support plate 34 is fixedly connected with four slide plates 35 distributed in rectangle, two groups of slide plates 35 distributed in left and right are slidably connected at the upper portion of two support tables 31, the front and rear sides of two support tables 31 are slidably connected with side plate 32, the opposite side of two side plates 32 is fixedly connected with two slide blocks one 33 distributed in left and right, two groups of slide blocks one 33 distributed in left and right are slidably connected at the front and rear portions of two support tables 31, the opposite side of two side plates 32 is movably connected with adjusting mechanism 6.

[0029] It should be noted that slope 1 has the basic functions of guiding vehicle to smoothly drive on test bench 2 and simulating uphill scene.Test bench 2 is used for carrying electric vehicle and collecting energy consumption data by test roller 7.Support table 31 is the main structure of support mechanism 3, and is slidably connected with test bench 2.Support table 31 provides mounting platform for support plate 34, side plate 32 and other components, to ensure the stability of the overall structure of support mechanism 3.Support plate 34 can be adjusted accordingly on support table 31 with the movement of test bench 2, and slide plate 35 is used to make support plate 34 stably slide above support table 31.Side plate 32 ensures that the relative position of adjusting mechanism 6 and support table 31 remains stable, and slide block one 33 is used to make side plate 32 stably slide on the front and rear sides of support table 31.Side plate 32 provides mounting base for adjusting mechanism 6, so that adjusting mechanism 6 can normally function and push test bench 2 to adjust the distance.

[0030] As shown in Figure 5As shown, the adjusting mechanism 6 comprises a motor 61 connected at the rear side of the rear side plate 32, the opposite sides of the two side plates 32 are jointly connected with a threaded rod 62, the rear end of the threaded rod 62 is fixedly connected to the output end of the motor 61, the lower part of the opposite side of the two support tables 31 is fixedly connected with a fixed block 65, the outer periphery of the threaded rod 62 is threadedly connected with a sliding block two 63, the upper and lower parts of the sliding block two 63 are rotatably connected with two left and right distributed connecting rods 64, and the ends away from the sliding block two 63 of the two groups of up and down distributed connecting rods 64 are rotatably connected to the upper and lower ends of the fixed block 65.

[0031] It should be noted that the adjusting mechanism 6 is the core component for realizing the distance adjustment of the test seat 2, so that the distance between the two test seats 2 can be flexibly adjusted according to the wheel distance requirements of different vehicle models. The motor 61 serves as the power source of the adjusting mechanism 6, and provides stable power for the entire distance adjustment process. The rotational movement of the threaded rod 62 is driven by the motor 61, and the threaded rod 62 converts the rotational movement into linear movement of the sliding block two 63, thereby pushing the test seat 2 to move and realize distance adjustment. The sliding block two 63 moves linearly along the axis of the threaded rod 62 when the threaded rod 62 rotates. The sliding block two 63 is connected to the fixed block 65 through the connecting rod 64, and converts the linear movement into horizontal movement of the test seat 2, thereby pushing the test seat 2 to change the distance. The stability and precision of the movement of the sliding block two 63 are crucial to the distance adjustment effect. The connecting rod 64 transmits the linear movement of the sliding block two 63 to the test seat 2. The fixed block 65 provides a rotating connection point for the connecting rod 64.

[0032] As shown in Figure 1 The front side of the front side plate 32 is fixedly connected with a test box 4, the upper part of the test box 4 is fixedly connected with a control panel, and the left and right sides of the test seat 2 are fixedly connected with two front and rear distributed connecting mechanisms 5.

[0033] It should be noted that the test box 4 serves as the data processing and control center, is responsible for receiving the instructions of the operator and real-time monitoring of the test data, ensures that the adjustment process meets the expectations, and guarantees the accuracy and safety of the test.

[0034] As shown in Figure 3 and Figure 4 The connecting mechanism 5 comprises a connecting block one 51, the opposite sides of the two groups of left and right distributed connecting block ones 51 are fixedly connected to the opposite sides of the two test seats 2 respectively, and the outer periphery of the two groups of left and right distributed connecting block ones 51 is slidingly connected to the lower part of the opposite side of the two slopes 1.

[0035] It should be noted that the connecting block one 51 is used to connect the test seat 2 and the slope 1, and the connecting block one 51 facilitates the installation and disassembly between the slope 1 and the test seat 2, and facilitates replacement and maintenance.

[0036] AsFigure 2 and Figure 3 As shown, two connecting blocks 52 are slidably connected to opposite sides of the two support platforms 31, and the opposite sides of the two connecting blocks 52 are respectively fixedly connected to opposite sides of the two test platforms 2.

[0037] It should be noted that the connecting block 2 52 is used to connect the test bench 2 and the support platform 31. The connecting block 2 52 facilitates the installation and disassembly of the test bench 2 and the support platform 31, and makes it convenient for replacement and maintenance.

The bolts 53 located on the opposite sides of the two ramps 1 all pass through the middle of the connecting block 1 51, and the bolts 53 located in the middle of the connecting block 2 52 all pass through the lower part of the opposite side of the two support platforms 31.

[0039] It should be noted that bolt 53 is used to fasten connecting block 51 to ramp 1 and connecting block 52 to support platform 31. Bolt 53 maintains a tight connection between the components, preventing loosening due to component movement and ensuring the structural stability of the entire test platform. At the same time, when the test platform needs to be adjusted or disassembled, loosening bolt 53 allows for convenient operation, improving the maintainability and flexibility of the equipment.

[0040] like Figure 6 As shown, the lower parts of the ramp 1, the test platform 2, and the support platform 31 are all rotatably connected to two sets of moving wheels 8 distributed in the front and rear.

[0041] It should be noted that the movable wheels 8 primarily serve to facilitate the overall movement and positioning of the equipment. When it is necessary to adjust the spacing between the test benches to adapt to different test sites or vehicle models, the operator can easily move the entire test bench using the movable wheels 8, quickly positioning it in the appropriate location. The movable wheels 8 are equipped with a braking device, which secures the test bench after it has been positioned, preventing movement during spacing adjustments and subsequent testing, thus ensuring the accuracy and safety of the tests.

[0042] The utility model discloses a working principle: need to assemble the equipment whole, insert the inside fixed test pedestal 2 of support table 31 with connecting block no. 2 52, subsequently connect and install with connecting block no. 1 51 and slope 1, then install bolt 53 with connecting block no. 1 51 and slope 1, connecting block no. 2 52 and support table 31 are fixed together.
