Description

Technical Field

[0001] This utility model belongs to the field of automotive testing technology, and in particular relates to a trolley for automotive side collision testing. Background Art

[0002] Car crash tests are the simplest and most direct way to obtain a car's safety performance data. By collecting various data points through crash tests, the quality of a car can be judged. Detailed crash test data not only fully conveys a car's parameters and strengths and weaknesses, prompting automakers to make positive improvements in subsequent production, but can also be used to set industry standards, continuously standardize industry production indicators, and deepen the automotive manufacturing industry.

[0003] In common crash tests, the trolleys used in side impact tests are often severely damaged by the reverse impact force and cannot be used for further crash testing. Furthermore, the relatively fragile trolleys cannot accurately measure the compressive strength of the car's side doors and B-pillars. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Combine Figures 1 to 4 The trolley shown is used for side impact testing of automobiles. It includes an impact head 1, a trolley support 2 on the side of the impact head 1, a reinforcing mechanism 3 on the top of the trolley support 2, a chassis frame 21, a reinforced chassis 22 on the inner side of the chassis frame 21, and two metal plates 23. The two ends of the metal plates 23 are connected to the chassis frame 21 by screws. Several metal rods 24 are passed through the inner side of the metal plates 23. The metal rods 24 are fastened by nuts after passing through the chassis frame 21. Several limiting square rods 25 are fixed on the top of the metal plates 23. A first mounting plate 26 is provided at one end of the chassis frame 21. The first mounting plate 26 is connected to the chassis frame 21 by welding.

[0023] The reinforcing mechanism 3 includes a frame plate 31. One end of the frame plate 31 is provided with a fixing plate 32. The fixing plate 32 is connected to the frame plate 31 and the chassis frame 21 by screws. The other end of the frame plate 31 is provided with a second mounting plate 33. The second mounting plate 33 is connected to the frame plate 31 and the first mounting plate 26 by screws. The frame plate 31 connects the trolley support 2 and the impact head 1, and can provide better support performance to prevent the trolley from falling apart after being impacted.

[0024] The second mounting plate 33 has several trapezoidal support plates 34 on its side. The trapezoidal support plates 34 are connected to the frame plate 31 and the second mounting plate 33 by screws. The trapezoidal support plates 34 provide support for the second mounting plate 33 and the impact head 1, so as to avoid large-area damage to the second mounting plate 33 and the impact head 1 after the trolley is impacted.

[0025] A semi-enclosed limiting plate 35 is provided above the frame plate 31. Both the semi-enclosed limiting plate 35 and the frame plate 31 are penetrated by the limiting square rod 25. The semi-enclosed limiting plate 35 and the limiting square rod 25 are fastened together by screws. A triangular limiting block 36 is fixedly provided above the side of the semi-enclosed limiting plate 35 near the trapezoidal support plate 34. The semi-enclosed limiting plate 35, the limiting square rod 25 and the frame plate 31 work together to form a solid structure that can withstand greater impact without being damaged.

[0026] Both the first mounting plate 26 and the second mounting plate 33 are provided with triangular impact-resistant blocks 37 on their sides. Several through holes 38 are provided at equal intervals on the triangular impact-resistant blocks 37. After the impact head 1 is impacted, the stable triangular structure of the triangular impact-resistant blocks 37 can resist the impact and will not deform significantly and damage other parts of the trolley.

[0027] The impact head 1 includes two crossbeams 11, and several fixing rods 12 are provided through the crossbeams 11. One end of the fixing rod 12 is provided with a limiting round head 13, and the other end of the fixing rod 12 passes through the through hole 38 and is inserted into the first mounting plate 26 and the second mounting plate 33. The fixing rod 12 is threadedly connected to the first mounting plate 26 and the second mounting plate 33. The fixing rod 12 connects the crossbeams 11 to the triangular impact block 37, so that the impact force of the crossbeams 11 is transmitted to the triangular impact block 37 in the first time.

[0028] The chassis frame 21 is equipped with four wheels 27, which are connected to the chassis frame 21 via a rotating shaft. A wedge plate 28 is fixedly installed below the reinforced chassis 22, and the wedge plate 28 is connected to an external power mechanism.

[0029] Working principle: During use, the trolley impacts the vehicle under test and receives a reverse impact force. The impact force is transmitted to the triangular impact-resistant block through the crossbeam. The stable triangular structure of the triangular impact-resistant block can resist the impact and prevent significant deformation and damage to other parts of the trolley. After the impact force is transmitted to the trolley body through the first mounting plate and the second mounting plate, the semi-enclosed limiting plate, the limiting rod, and the frame plate work together to form a solid structure, so that the trolley can withstand the impact without being damaged. The remaining impact force is transmitted and dispersed along the metal plate and the metal rod to the trolley bracket for further distribution.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
