Description

Technical Field

[0001] The utility model relates to the technical field of automobile chassis optimization equipment, and particularly provides an automobile chassis structure optimization device. Background Technique

[0002] The automobile chassis is composed of four parts: a powertrain, a running gear, a steering system, and a braking system. The function of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the automobile, and receive the power of the engine to make the automobile move and ensure normal driving.

[0003] At present, the conditions on ordinary roads are complex. On many roads, especially those often passed by heavy trucks, there are many potholes and gravels. When our vehicle drives on such roads, if we are not careful, the gravels and the like will come into close contact with the chassis of our own vehicle, and in severe cases, the parts located in the chassis part will be damaged. Generally, in order to prevent damage to the chassis, the vehicle can often install a "chassis armor", that is, steel plates with high structural strength, etc., to protect important parts such as the engine and the water tank.

[0004] However, after installing the chassis armor, it has virtually increased the weight of the vehicle, and the fuel consumption during driving has also increased. Since various parts under the automobile chassis are mostly located on different horizontal planes, that is, at different distances from the ground, when gravel on the ground hits the parts, the impact force and damage degree generated on the parts are different. Similarly, when being impacted by gravel, some parts are vulnerable, and some parts can withstand a certain degree of impact. Therefore, installing the chassis armor at a suitable position is an important research direction for optimizing the automobile chassis structure.

[0005] Therefore, we propose to design an automobile chassis structure optimization device. Content of the Utility Model

[0006] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the implementation mode of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please refer to Figures 1-4 , the present utility model provides an optimization device for an automobile chassis structure, including a base 1. Both sides of the top of the base 1 are fixedly connected with guard plates 2. Ramps 3 are arranged at both ends of the top of the base 1. A flap 4 is arranged at the top of the ramp 3. The top of the flap 4 is hinged to the top end of the ramp 3 and can be flipped during the optimization work to assist in closing the optimization environment. Anti-slip patterns are arranged on the surface of the flap 4. Both the guard plate 2 and the flap 4 are made of wear-resistant steel plates, which is convenient for driving the vehicle to be optimized through the ramp 3 to the top of the base 1.

[0029] In this embodiment, a bolt 7 is arranged through the side of the guard plate 2, and a pin hole 8 corresponding to the bolt 7 is opened on the side of the flap 4. The guard plate 2 and the flap 4 are connected by the bolt 7, so as to facilitate the fixation of the flap 4.

[0030] Wheel grooves 5 are arranged at the four corners of the top of the base 1. Both sides of the inner wall of the wheel groove 5 are inclined, and the middle of the wheel groove 5 is concave. The side of the wheel groove 5 is correspondingly connected to the recovery groove 6, which is convenient for positioning and indicating the vehicle. That is, when the vehicle tires are respectively located in the four wheel grooves 5, it means that the vehicle has reached the optimization test site. Among them, the internal distance of the wheel groove 5 is long and the width is sufficient, and it can be applied to the optimization test of vehicle chassis with various wheelbases.

[0031] Recovery grooves 6 are provided on both sides of the wheel groove 5. The recovery grooves 6 can collect the fired steel balls, facilitating subsequent reuse and filling.

[0032] A firing assembly 9 is fixedly connected to the inside of the base 1 by embedding. The firing assembly 9 includes a device rack 10 fixed inside the base 1. The cross-section of the device rack 10 is in the shape of a "king" character, which is convenient for adapting to the shapes of most vehicle chassis on the market, and the test surface can cover most areas of the vehicle chassis.

[0033] U-shaped air pipes 11 are fixedly connected to both ends inside the device rack 10 by embedding. One end of the U-shaped air pipe 11 is provided with a high-pressure air pump 12, a branch pipe 13 is provided in the middle of the U-shaped air pipe 11, firing heads 14 are provided at the tops of the U-shaped air pipe 11 and the branch pipe 13, and a wide-mouth slideway 15 is opened at the top of the device rack 10.

[0034] The firing head 14 includes a fixed pipe 141. An electromagnetic valve 142 is arranged inside the fixed pipe 141. Through external PLC programming, precise control of the opening and closing of each electromagnetic valve 142 can be achieved, which is convenient for controlling the opening and closing of the pipeline according to the optimized test situation of the chassis. A central pipe 143 is arranged at the top of the fixed pipe 141. Emitters 144 are arranged obliquely on the periphery of the central pipe 143. The central pipe 143 and the emitters 144 are both connected to the inside of the fixed pipe 141 and rubber rings are fixedly connected at the pipe orifices. When testing, the steel balls are placed on the top of the fixed pipe 141. Under the action of the rubber rings, it is convenient to position the steel balls.

[0035] The exhaust end of the high-pressure air pump 12 is connected to the inside of the U-shaped air pipe 11. High pressure is provided to the U-shaped air pipe 11 through the high-pressure air pump 12. When the electromagnetic valve 142 is opened, a high-pressure air flow can be quickly generated in the firing head 14 to fire the steel balls, making them hit the vehicle chassis at high speed.

[0036] Among them, the tops of the firing heads 14 correspond to the wide-mouth slideways 15 one by one. The cross-section of the wide-mouth slideway 15 is in a fan shape. The central angle of the cross-section of the wide-mouth slideway 15 is 120 degrees. The fan-shaped slideway structure is convenient for adapting to the firing heads 14 to fire the steel balls from different directions.

[0037] During use, first, several steel balls are scattered and put into the wide-mouth slideways 15 respectively, making them fall on the rubber rings. That is, at most four steel balls can be accommodated in each wide-mouth slideway 15, and the four steel balls correspond to the orifices of the central pipe 143 and the three emitters 144 respectively.

[0038] Subsequently, the vehicle is driven to the top of the base 1. The four wheels are respectively located in the four wheel grooves 5. After the flap 4 is flipped to the vertical state, it is fixed to the guard plate 2 by the bolt 7, forming a protective structure around the vehicle to prevent the steel balls from falling out when they fall after hitting the chassis.

[0039] At this time, start the high-pressure air pump 12 to generate high pressure in the U-shaped air pipe 11 and the branch pipe 13. Subsequently, the opening and closing of the solenoid valve 142 are realized through external PLC programming. When the solenoid valve 142 is opened, the fixed pipe 141 is connected to the corresponding U-shaped air pipe 11 and branch pipe 13, and the high-pressure air flow instantly sprays out from the central pipe 143 and the firing pipe 144, ejecting the steel balls, which hit the car chassis. During the test, some solenoid valves 142 can also be closed to conduct targeted impact tests on different areas of the chassis.

[0040] In each firing head 14, the steel balls fired by the central pipe 143 impact the car chassis in the vertical direction, while the firing pipes 144 on its periphery fire the steel balls at different angles. The specific angles can be set according to the actual optimization test situation.

[0041] After the steel balls impact the chassis, some fall on the base 1 and then re-enter the wide-mouth slideway 15. At this time, when the solenoid valve 142 is opened again, some of the returned steel balls can be fired a second time and impact the car chassis again, fully simulating the uncertain factors on the road conditions. Among them, some steel balls fall from the base 1 into the wheel groove 5 and then enter the recovery groove 6 for accumulation. A certain slope can be set for the wheel groove 5 so that the steel balls can completely slide into the recovery groove 6, facilitating subsequent recovery and reuse.

[0042] Repeat the firing multiple times in this way, and judge the number of remaining steel balls that can be fired by the sound of the steel balls hitting after firing. After several rounds of shooting, drive the vehicle away from the base 1 and raise the vehicle. Evaluate the damage condition of the vehicle chassis parts, install chassis armor at the positions with serious damage, use chassis armor with lighter weight and general structural strength at the positions with general damage, and do not install chassis armor at the positions without damage, so as to reasonably optimize the vehicle chassis.

[0043] Although the present invention has been described with reference to the embodiments above, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
