[0016] The utility model will be further described below in combination with the drawings and examples:
[0017] A vehicle battery simulation scraping device, referring to Figs. 1 to 3 , including base 1, the center part above and below of base 1 is provided with chute 2, the inside of chute 2 is slidably connected with scraping head 3, the upper side of base 1 is fixedly connected with guide structure, and scraping head 3 is located in the inside of guide structure, a plurality of through holes 4 are provided between the upper side and the lower side of base 1, the upper side of base 1 is fixedly connected with mounting strip 5, a plurality of mounting holes 6 are provided in the upper side of base 1, and the mounting holes 6 are located between two mounting strips 5. The mounting holes 6 on the base 1 cooperate with the mounting strips 5, the mounting position of the guide structure can be flexibly adjusted, thereby changing the spacing between the two guide structures. By moving the fixing position of the fastener in different mounting holes 6, different sizes of scraping heads 3 can be adapted, so that the same device is suitable for various test requirements, improving the versatility and test efficiency.
[0018] The guiding structure of the embodiment comprises two L-shaped plates 7 above the base 1, and a space for the scraping head 3 to move is left between the two L-shaped plates 7, and the scraping head 3 is in the space. The moving space between the two L-shaped plates 7 forms a stable guiding channel, and when the scraping head 3 slides in the channel, the side walls of the L-shaped plates 7 can effectively limit the lateral deviation of the scraping head 3, so as to ensure that the scraping head 3 always moves along the predetermined track. This guiding mode avoids deviation or stagnation caused by uneven force during scraping, so that the test action is more accurate and reliable.
[0019] In the embodiment, straight grooves 8 compatible with the L-shaped plates 7 are formed on both sides of the scraping head 3, and the L-shaped plates 7 are slidingly fitted in the grooves. The grooves avoid the situation that the scraping head 3 is suspended later.
[0020] In the embodiment, the scraping head 3 is a cylindrical structure, and the upper end thereof is one of a circular structure and a conical structure. The circular structure of the upper end of the scraping head 3 can simulate the scraping bottom condition of a vehicle rolling over a smooth protruding object such as a manhole cover or a deceleration strip, and the conical structure can reproduce the impact effect of hitting a sharp obstacle such as a stone or a curb. This replaceable head design makes a single set of device cover a variety of actual road conditions from gentle scraping to severe impact, which significantly improves the coverage range of the test scene.
[0021] In the embodiment, the scraping head 3 is fixedly connected with a guide block 9 sliding in the sliding groove 2, and the two sides of the guide block 9 are arc-shaped structures compatible with the cylindrical structure of the scraping head 3. The two ends of the inner wall of the sliding groove 2 are semicircular structures to adapt to the arc-shaped structure of the guide block 9. The cooperation of the arc-shaped guide block 9 and the semicircular sliding groove 2 makes the scraping head 3 naturally and smoothly turn when moving, avoiding jamming or eccentric wear. The arc-shaped side surface of the guide block 9 perfectly fits the sliding groove 2, which not only ensures the stability of the movement of the scraping head 3, but also effectively disperses the impact force, prolongs the service life of the device. The whole movement process is more stable and reliable, ensuring the accuracy of each test.
[0022] The preferred embodiments disclosed in the utility model are not limited to the above, and those skilled in the art can easily understand the spirit of the utility model and make different inferences and changes according to the above embodiments, as long as they do not deviate from the spirit of the utility model, they are within the protection scope of the utility model.
