[0028] As shown in Figures 1-5, the specific scheme of the embodiment is as follows: A vehicle dynamometer with energy transmission function, characterized in that it includes an experimental chamber 1, which includes a first chamber 11 and a second chamber 12. The internal net space dimensions of the experimental chamber 1 are at least 28000×6000×6000 (D depth × W width × H height, in mm), capable of accommodating various types of vehicles for testing, ensuring the diversity and adaptability of the tests. The dimensions of the first chamber 11 are ≥14000×6000×6000 mm, and the dimensions of the second chamber 12 are ≥14000×6000×6000 mm. The first chamber 11 and the second chamber 12 increase the flexibility and efficiency of the tests, and can work independently or in combination to meet different testing needs. When conducting temperature shock tests, one of them is... The test chamber consists of a high-temperature chamber and a low-temperature chamber, each with its own temperature adjustable to the required range. The large size of the first chamber 11 and the second chamber 12 ensures that the test vehicle has sufficient space for various performance tests. At the same time, the adjustable temperature function allows the test to cover various environmental conditions such as high temperature, low temperature and temperature shock, improving the comprehensiveness and accuracy of the test. An underground space is provided on the first chamber 11, which reduces ground occupation and reduces the impact of noise and vibration on the test. The inner side of the test chamber 1 is equipped with a high and low temperature control system, which can adjust the high and low temperature of the first chamber 11 and the second chamber 12 to simulate the test temperature under different environmental conditions, ensuring the accuracy and reliability of the test results, helping to evaluate the performance of the whole vehicle at different temperatures, and providing important basis for vehicle design and improvement.

[0029] A sliding partition 13 is provided between the first compartment 11 and the second compartment 12. The sliding partition 13 can separate the first compartment 11 and the second compartment 12, and its position can be adjusted as needed to change the layout of the experimental compartment 1, increasing the flexibility and versatility of the experimental compartment 1. The separation state between the compartments can be quickly adjusted according to different testing needs, improving testing efficiency and convenience. A dynamometer 14 is provided inside the first compartment 11. The dynamometer 14 is located inside the underground space. By precisely controlling the output of the dynamometer 14, the driving state of the vehicle under different road conditions and loads can be simulated, thereby comprehensively evaluating the power performance and economy of the whole vehicle.

[0030] The experimental chamber 1 is provided with an installation groove 2, which is symmetrically distributed on the inner side of the first chamber 11 and the second chamber 12 with the sliding partition 13 as the center point. The inner side of the installation groove 2 is provided with an installation seat 3, the thickness of which is less than the depth of the installation groove 2. The installation seat 3 is connected to the installation groove 2 by a fixing screw 302. The installation seat 3 is provided with a sliding rod 4, and the surface of the installation seat 3 is provided with a fixing groove 301 for mounting the sliding rod 4. The sliding rod 4 is fitted with a sliding seat 5. Both the fixing groove 301 and the sliding seat 5 are rectangular. The sliding seat 5 is provided with an installation plate 6. There are two installation plates 6, which are symmetrically distributed. The surface of each pair of installation plates 6 is provided with a plurality of installation holes 601.

[0031] The design of the mounting slot 2, mounting base 3, sliding rod 4 and sliding seat provides an installation and adjustment mechanism for the charging box 7, ensuring that the charging box 7 can be stably and flexibly installed on the experimental chamber 1 and its position can be adjusted as needed. This design makes the installation and disassembly of the charging box 7 simple and quick, and at the same time, the position of the charging box 7 can be quickly adjusted according to the position of the test vehicle, improving the convenience and flexibility of the test.

[0032] A charging box 7 is installed at the end of the mounting plate 6 away from the sliding seat 5. A main power source 702 is connected to the charging box 7. The charging box 7 can provide energy to the test vehicle and simulate the charging process during actual driving. By connecting the main power source 702 and the charging box 7, energy can be delivered to the test vehicle, and its performance indicators such as charging speed and efficiency under different charging conditions can be evaluated. The main power source 702 is located in the gap between the mounting seat 3 and the mounting groove 2. The main power source 702 can extend with the movement of the charging box 7. A connecting block 701 is installed on the outside of the charging box 7. The connecting block 701 is connected to the mounting hole 601 by fastening bolts.

[0033] The mounting plate 6 is provided with a locking component 8, which includes a fixed base 81 installed on the outside of the mounting plate 6. A pair of locking rods 82 are movably connected to one end of the fixed base 81 near the mounting base 3. A through hole 811 is opened at the end of the fixed base 81 near the mounting base 3 for the locking rods 82 to slide. A positive magnetic plate 83 is fixedly connected to one end of the locking rod 82 on the inner side of the fixed base 81. A return spring 84 is fixedly connected between the positive magnetic plate 83 and the inner side wall of the fixed base 81. An electromagnetic plate 85 is installed on the inner side wall of the fixed base 81 and is aligned with the position of the positive magnetic plate 83. The magnetic force generated by the electromagnetic plate 85 after being energized is positive. A rubber pad 851 is fixedly connected to one end of the electromagnetic plate 85 near the positive magnetic plate 83. The distance between the pair of locking rods 82 is twice the diameter of the sliding rod 4.

[0034] The mounting base 3 has several locking slots 9 that cooperate with the locking component 8. These locking slots 9 are symmetrically distributed and their specifications match the specifications of the locking rod 82. When the electromagnetic plate 85 is energized, it generates a positive magnetic force. Through the principle of like poles repulsion, the positive magnetic plate 83 drives the locking rod 82 to move. Simultaneously, the positive magnetic plate 83 compresses the return spring 84, thereby engaging and locking the locking rod 82 with the locking slot 9, thus fixing the position of the charging box 7. When the electromagnetic plate 85 is de-energized, the... When the electromagnetic plate 85 loses its magnetism, the positive magnetic plate 83 moves in position due to the elastic force of the return spring 84, thereby separating its locking rod 82 from the locking groove 9. This allows the charging box 7 to move in position. After the charging box 7 moves to the designated position, the locking component 8 locks it in a fixed position by electromagnetic force, preventing shaking or displacement during the test. This ensures the stability and safety of the charging box 7 during the test, improves the accuracy and reliability of the test, and the locking and unlocking process is simple and quick, making it easy to quickly adjust the position of the charging box 7 during the test.

[0035] The operation steps of the above embodiment are as follows:

[0036] The new energy vehicle to be tested is parked on the dynamometer 14 inside the first compartment 11 or inside the second compartment 12, ensuring that the vehicle is aligned and connected with the dynamometer 14.

[0037] By sliding the sliding seat 5 on the sliding rod 4, the charging box 7 is adjusted to a suitable position. When the charging box 7 is moved to the designated position, the magnetic force generated by the energization of the electromagnetic plate 85 causes the positive magnetic plate 83 to drive the locking rod 82 to engage and lock with the locking groove 9 on the mounting seat 3, thereby fixing the position of the charging box 7 and connecting the charging gun of the charging box 7 to the charging interface of the vehicle.

[0038] The sliding partition 13 is closed by controlling the control system, and the dynamometer 14 or the high and low temperature control system or both are started.

[0039] When the high and low temperature control system is started, the temperature of the first chamber 11 and the second chamber 12 are adjusted to the specified range by the high and low temperature control system respectively. For example, when conducting a temperature shock test, one chamber is set to high temperature and the other is set to low temperature. After the rated time temperature control, the sliding partition 13 is opened by the control system to conduct the shock test and observe the impact of the shock test on energy transmission.

[0040] When the dynamometer 14 is started, the output of the dynamometer 14 is precisely controlled to simulate the driving state of the vehicle under different road conditions and loads. At the same time, the environmental control device is turned on to conduct tests in humid and hot environment, solar radiation environment, and fresh air environment. Various data during the test process are monitored in real time to ensure the accuracy and reliability of the test.

[0041] After the test, the test vehicle will be removed from test chamber 1 in preparation for the next round of testing or other processing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
