Description

Technical Field

[0001] The utility model relates to the technical field of chassis skeleton structures, and particularly relates to an automobile chassis skeleton structure. Background Art

[0002] An 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 engine and its various components and assemblies of the automobile, form the overall shape of the automobile, and receive the power of the engine to make the automobile move and ensure normal driving. When transporting goods or materials, pickup trucks are usually used for transportation. However, the chassis skeleton of existing pickup trucks may be relatively low. When the vehicle travels on rough or low ground, it may touch the vehicle chassis, which will not only impact and damage the chassis of the pickup truck, but also cause the cargo bed to shake due to the impact, and thus the transported materials may shake down.

[0003] In search of solutions to the above problems, it is found that in the currently disclosed prior art, such as a high-strength automobile chassis skeleton proposed in the publication number CN211442211U, a first protection plate is installed at the bottom end of the chassis skeleton through a spring, and one end of the first protection plate is rotatably installed at the bottom end of the chassis. A second protection plate is installed at the bottom end of the first protection plate through a spring again. When the vehicle travels on low ground, the second protection plate contacts the ground, rises by squeezing the spring, the second protection plate squeezes the first protection plate, and the first protection plate buffers under the extrusion of the spring, thereby protecting the vehicle chassis.

[0004] However, when squeezing the first protection plate and the second protection plate, the spring may move up and down repeatedly, causing the protection plate to move up and down. When the vehicle travels on high ground, the protection plate may still be moving up and down, thus contacting the ground to form friction, which affects the driving of the vehicle.

Detailed implementation manner

[0028] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0029] As Figures 1 to 5 shown, this embodiment proposes an automotive chassis frame structure, including a frame body 1, a lifting component, a protection plate 2, a rotating frame 3, a sliding component, a fixing component, and an adjusting component. A plurality of through grooves and sliding grooves are opened at the bottom end and side surface of the frame body 1. Four lifting components are provided, and every two of the four lifting components form a group. The lifting components are arranged in the through grooves of the frame body 1. The protection plate 2 is arranged on the lifting components. A plurality of rotating frames 3 are provided, and the plurality of rotating frames 3 are fixedly installed on the protection plate 2. A plurality of sliding components are provided, and the plurality of sliding components are arranged on the rotating frames 3 and the frame body 1. Two fixing components are provided, and the two fixing components are respectively arranged on both sides of the protection plate 2. A plurality of adjusting components are provided, and the plurality of adjusting components are arranged on the frame body 1. When the vehicle travels on a lower road surface, the road surface can first contact the protection plate 2. Both sides of the protection plate 2 are set to be arc-shaped, so as to better squeeze the protection plate 2 to move it upward. The protection plate 2 moves up and down through the lifting component, and can be buffered during the movement through the sliding component, avoiding touching the bottom end of the frame body 1 due to a too fast upward movement speed. After the upward movement is completed, the protection plate 2 can be fixed above through the fixing component and the adjusting component, thus avoiding the reciprocating up and down movement of the protection plate 2.

[0030] In this embodiment, referring to Figure 2 , the lifting assembly includes a lifting cylinder 101, a lifting column 102, and a connecting block 103. The lifting cylinder 101 is fixedly installed in the through groove of the frame 1, and a sliding groove is provided inside the lifting cylinder 101. The lifting column 102 is slidably installed in the sliding groove of the lifting cylinder 101. The connecting block 103 is fixedly installed at the bottom end of the lifting column 102, and the side surface of the connecting block 103 is fixedly connected to the side surface of the protection plate 2. After the protection plate 2 contacts the ground, the ground exerts pressure on it, and the protection plate 2 drives the connecting block 103 and the lifting column 102 to move upward in the lifting cylinder 101. Thus, the lifting column 102 can drive the fixing assembly to contact the adjusting assembly, so as to fix the subsequent protection plate 2.

[0031] In this embodiment, referring to Figure 3 , the sliding assembly includes a sliding box 201, a sliding frame 202, and rollers 203. The sliding box 201 is fixedly installed at the bottom end of the frame 1. The sliding frame 202 is rotatably installed in the rotating frame 3, and the rollers 203 are rotatably installed on the sliding frame 202, and the rollers 203 are in contact with the inside of the sliding box 201. When the protection plate 2 moves upward, it rotates by squeezing the sliding frame 202. The top end of the roller 203 is in contact with the inner top wall of the sliding box 201, and the roller 203 can slide inside the sliding box 201. The sliding frame 202 drives the roller 203 to slide inside the sliding box 201, so as to buffer the upward movement of the protection plate 2.

[0032] In this embodiment, referring to Figure 4 , the fixing assembly includes a connecting plate 301, a sliding plate 302, a fixing frame 303, and a spring 304. The connecting plate 301 is fixedly installed between each group of lifting columns 102. There are four sliding plates 302. Every two of the four sliding plates 302 form a group, and each group of sliding plates 302 is fixedly installed on the side surface of the connecting plate 301, and a sliding groove is provided on the side surface of the sliding plate 302. There are two fixing frames 303, and the two fixing frames 303 are respectively slidably installed in the sliding grooves between each group of sliding plates 302. There are two springs 304, and the two springs 304 are respectively installed on the side surface of the connecting plate 301, and the other end of the spring 304 is fixedly connected to the side surface of the fixing frame 303. When the lifting column 102 moves upward, it can drive the connecting plate 301 to move upward. After moving upward, the fixing frame 303 contacts the hook 406, and the hook 406 squeezes the fixing frame 303 and the spring 304 to slide between the sliding plates 302. After being squeezed, through the elongation of the spring 304, the fixing frame 303 can be pushed forward. The adjusting block 403, the hook 406, and the fixing frame 303 are all located in the same vertical position, so that the hook 406 can hook the fixing frame 303, thereby fixing the protection plate 2.

[0033] In this embodiment, referring to Figure 5, The adjusting assembly includes a cylinder 401, an adjusting plate 402 and an adjusting block 403. The cylinder 401 is installed on the side of the frame 1. There are two adjusting plates 402, and the two adjusting plates 402 are respectively slidably installed in the sliding grooves on the side of the frame 1. The adjusting block 403 is fixedly installed between the two adjusting plates 402, and the top end of the adjusting block 403 is fixedly connected to the output end of the cylinder 401. When it is necessary to loosen the fixing frame 303, the cylinder 401 can be started, and the cylinder 401 pushes the adjusting plate 402 to slide downward on the side of the frame 1, thereby driving the adjusting block 403 and the hook 406 to move downward.

[0034] In this embodiment, referring to Figure 5 , the adjusting assembly further includes a fixing plate 404, a rotating block 405, a hook 406 and a motor 407. There are two fixing plates 404, and the two fixing plates 404 are fixedly installed at the bottom end of the adjusting block 403. The rotating block 405 is rotatably installed between the two fixing plates 404. The hook 406 is fixedly installed at the bottom end of the rotating block 405. The motor 407 is installed on the side of the fixing plate 404, and the output end of the motor 407 is fixedly connected to the side of the rotating block 405. After the hook 406 is moved downward by a certain distance, the motor 407 can be started, and the motor 407 drives the rotating block 405 and the hook 406 to rotate, so that when the fixing frame 303 moves downward, it can avoid contacting the hook 406, so that the protection plate 2 can move to its original position.

[0035] In this embodiment, when the structure protects the frame 1, first, when the tire 4 moves and drives the car to an uneven ground or a lower ground, the ground will contact and squeeze the protection plate 2. When the protection plate 2 moves upward, it drives the connecting block 103 and the lifting column 102 to slide upward in the lifting cylinder 101, and can squeeze the sliding frame 202 to rotate on the rotating frame 3, and the sliding frame 202 drives the roller 203 to slide in the sliding box 201, so as to buffer the protection plate 2 during the upward movement. During the upward movement, the fixing frame 303 contacts the hook 406. By squeezing the fixing frame 303 through the hook 406, the fixing frame 303 can slide in the sliding plate 302. After the fixing frame 303 moves to a position where it does not contact the hook 406, the retraction of the spring 304 can squeeze the fixing frame 303 to move forward, so that the hook 406 hooks the fixing frame 303 and fixes the protection plate 2, avoiding the protection frame from moving up and down and contacting the ground again to cause friction after the protection of the frame 1 is completed. If passing through a lower ground again, the cylinder 401 can be started, the cylinder 401 pushes the adjusting block 403 to drive the hook 406 to move downward, and then the motor 407 is started to drive the rotating block 405 and the hook 406 to rotate, so that the hook 406 is disengaged from the fixing frame 303, and the fixing frame 303 moves down to its original position, so as to carry out subsequent protection again.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
