Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, and in particular relates to an automobile body floor flipping mechanism. Background Technology

[0002] The vehicle floor is the supporting and protective structure at the bottom of the vehicle. It is made of high-strength steel or aluminum alloy and has impact resistance and collision protection performance. It covers the entire bottom of the vehicle, provides support for the interior space, and installs key components such as the suspension system, engine, and transmission. The processing of the vehicle floor requires flipping the floor, so a flipping mechanism is needed.

[0003] A search revealed Chinese Patent Publication No. CN222244528U, which discloses a car body floor tilting mechanism. The mechanism includes a storage plate, a housing fixedly connected to the upper surface of the storage plate, a second motor fixedly connected inside the storage plate, a gear fixedly connected to the output end of the second motor, a rack meshing with the outer wall of the gear, a rectangular block fixedly connected to the right outer wall of the rack, a slide rail slidably connected to the lower surface of the rectangular block, the lower surface of the slide rail fixedly connected to the upper surface of the storage plate, and a clamping plate fixedly connected to the outer wall of the rectangular block. The lower surface of the clamping plate slidably connects to the upper surface of the storage plate. In this invention, the second motor drives the gear to rotate, which in turn drives the rack to slide inside the limiting block. Simultaneously, the rack drives the rectangular block to slide on the slide rail, and the clamping plate to slide on the storage plate. This allows for rapid clamping of the car body floor, reducing workpiece clamping time.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: most existing flipping mechanisms are based on the dimensions of the vehicle's floorboards, which limits the applicability of the flipping mechanism and reduces its practicality. Furthermore, most current flipping mechanisms are driven by motors, and due to the lack of safety mechanisms, dangerous situations such as rebound can easily occur during the flipping process, reducing the safety of the flipping mechanism.

[0005] Therefore, this utility model provides a car body floor flipping mechanism to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0021] In specific implementation, such as Figures 1-4As shown, this utility model provides a technical solution: a car body floor flipping mechanism, including a base 1, a guide rail 5 fixedly installed on the upper surface of the base 1, and a slider 6 slidably installed on the outer surface of the guide rail 5; a mounting seat 2, a reduction motor 3 fixedly installed on the upper surface of the mounting seat 2, and a connecting rod fixedly installed at the output end of the reduction motor 3; and a flipping assembly 4, which is disposed on the upper surface of the symmetrical slider 6 and is used to clamp and flip the car body floor; wherein, the flipping assembly 4 includes a connecting seat 41 and a fixing clamp 49, the lower surface of the connecting seat 41 is fixedly connected to the upper surface of the slider 6, a plurality of support plates 42 are fixedly installed on the upper surface of the connecting seat 41, a bearing sleeve 43 is fixedly installed between the support plates 42, a positioning plate 44 is fixedly installed on the outer surface of the bearing sleeve 43, and a plurality of equidistant positioning holes 45 are provided on the side wall of the positioning plate 44.

[0022] A rotating rod 46 is rotatably mounted on the inner wall of the bearing sleeve 43. A flip plate 47 is fixedly mounted on one end of the rotating rod 46, and one end of the other rotating rod 46 is fixedly connected to one end of the connecting rod at the output end of the geared motor 3.

[0023] A cylinder 48 is fixedly installed on the side wall of the flip plate 47. A positioning pin is fixedly installed at one end of the cylinder 48, and one end of the positioning pin is adapted to the positioning hole 45.

[0024] The side wall of the fixing clamp 49 is fixedly connected to the side wall of the flip plate 47, and a self-locking bolt 410 is threaded on the inner wall of the fixing clamp 49.

[0025] One end of the self-locking bolt 410 extends into the interior of the fixing clip 49, and a positioning clip 411 is rotatably mounted on one end of the self-locking bolt 410. The positioning clip 411 is made of rubber.

[0026] Specifically, by setting the flipping component 4, the vehicle body floor is clamped and flipped. The vehicle body floor is placed between the fixing clamps 49, and then by rotating the self-locking bolt 410, the positioning clamp 411 and the fixing clamp 49 cooperate to clamp and fix the vehicle body floor under the action of the thread, thereby fixing the vehicle body floor between the two flipping plates 47. Then, the reduction motor 3 drives the rotating rod 46 to rotate in the bearing sleeve 43 through the connecting rod. At this time, the rotating rod 46 drives the flipping plate 47 to rotate, thereby driving the vehicle body floor to flip through the fixing clamp 49. After the vehicle body floor is flipped to the appropriate position, the cylinder 48 drives the positioning pin to move towards the positioning plate 44, so that one end of the positioning pin is inserted into the positioning hole 45, thereby limiting the flipping plate 47.

[0027] The side wall of the mounting base 2 is fixedly connected to the side wall of one of the support plates 42. A fixing base 8 is fixedly installed on the side wall of the connecting base 41, and an electric telescopic rod 7 is fixedly installed between the fixing bases 8.

[0028] A telescopic rod 9 is fixedly installed on the side wall of the support plate 42, and a connecting cylinder is fixedly installed on the side wall of the other support plate 42. One end of the telescopic rod 9 is fixedly connected to the inner wall of the connecting cylinder.

[0029] Specifically, by setting the electric telescopic rod 7, the flipping mechanism can be adapted to different sizes of vehicle chassis. The retraction and extension of the electric telescopic rod 7 will drive the fixed seat 8 to move synchronously. At this time, the fixed seat 8 will drive the connecting seat 41 to slide on the guide rail 5 on the base 1 under the limit of the slider 6, thereby adjusting the distance between the two flipping components 4 and the distance between them, so that the flipping mechanism can meet the needs of different sizes of vehicle chassis. When the distance between the flipping plates 47 is adjusted, the telescopic rod 9 will also retract and extend synchronously.

[0030] The electric telescopic rod 7 extends and retracts, thereby driving the flipping assembly 4 to slide on the guide rail 5 via the slider 6 through the fixed seat 8. This adjusts the distance between the two flipping assemblies 4 so that the distance between the two flipping assemblies 4 matches the vehicle floor. Then, the vehicle floor is fixed by the flipping assembly 4. During the processing of the vehicle floor, the reduction motor 3 drives the flipping assembly 4 to work and drive the vehicle floor to flip.

[0031] The above provides a detailed description of the automobile body floor tilting mechanism provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
