Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame processing technology, and in particular to an electric vehicle frame bending device with a protective structure. Background Technology

[0002] The frame of an electric vehicle is the core supporting structure of the vehicle. It supports key components such as the vehicle body, battery, motor, and controller, and must ensure stability and safety during riding. The frame of an electric vehicle is usually made of multiple alloy tubes welded or spliced ​​together. Some of these tubes need to be bent to reduce welding points or connection points, thereby improving the main structural strength of the electric vehicle frame.

[0003] Currently, two sets of clamping blocks are typically used to hold the pipe at the bending point, and then the unbent end of the pipe is limited. Then, one set of clamping blocks is rotated to bend the pipe. During the bending process, there is a lack of effective protective structure, which can easily cause the pipe to pop out and cause safety accidents, posing certain safety hazards.

[0004] Therefore, to address the above issues, an electric vehicle frame bending device with a protective structure can be designed. This device can fix and limit both ends of the tube during bending operations, preventing the tube from accidentally popping out during bending and causing a safety accident, thus enhancing safety. Utility Model Content

[0005] In order to overcome the problem that the current electric vehicle frame bending device lacks an effective protective structure during the bending process, which can easily cause the pipe to pop out and cause safety accidents, and has certain safety hazards.

[0006] The technical solution of this utility model is as follows: an electric vehicle frame bending device with a protective structure, including a frame, a rotating shaft, a bending assembly, a drive assembly, a mounting assembly, and a limiting block. The rotating shaft is rotatably connected to the inside of the frame. The bending assembly is disposed on the periphery of the rotating shaft. The drive assembly is disposed at one end of the rotating shaft. The mounting assembly is disposed on one side of the bending assembly. The limiting block is disposed inside the mounting assembly. A protective bracket is fixedly installed on the periphery of the rotating shaft. A notch is opened inside the protective bracket. A mounting plate is fixedly installed on one side of the limiting block. A pull rod is slidably connected inside the mounting plate. A spring is fixedly installed between the pull rod and the mounting plate. A conical plug is fixedly installed at one end of the pull rod.

[0007] Preferably, a rotating shaft is used to support and install the bending assembly, an installation assembly is used to support and install the limiting block, and a drive assembly is used to drive the rotating shaft to rotate, thereby causing the bending assembly to rotate. In conjunction with the limiting block, the tubes of the electric vehicle frame are bent. An installation plate is used to install the pull rod. Before the bending operation, by pulling the pull rod to compress the spring, a tapered plug can be inserted into the interior of the bent tube. The tapered plug can adapt to the inner diameter of tubes of different specifications, and the other end of the tube passes through the protective bracket through the notch, thereby limiting and fixing both ends of the tube, preventing the tube from accidentally springing up during the bending process and causing a safety accident.

[0008] Preferably, the bending assembly includes a rotating bracket, a support plate, and a first telescopic rod. The rotating bracket is fixedly installed on the periphery of the rotating shaft, the support plate is slidably connected to the upper end of the rotating bracket, and the first telescopic rod is hinged inside the rotating bracket, with the output end of the first telescopic rod hinged to the support plate.

[0009] Preferably, the bending assembly includes a first clamping block and a second clamping block. The first clamping block is fixedly installed on the upper end of the support plate, and the second clamping block is fixedly installed on the periphery of the rotating shaft. The first clamping block and the second clamping block correspond to each other.

[0010] Preferably, the drive assembly includes a motor and a gearbox. The motor is fixedly installed inside the frame, the gearbox is located on one side of the motor, the input end of the gearbox is fixedly connected to the output end of the motor, and the output end of the gearbox is fixedly connected to the rotating shaft.

[0011] Preferably, the mounting components include a sliding bracket and a guide rail, with the guide rail fixedly mounted on the upper end of the frame and the sliding bracket slidably connected to the frame via the guide rail.

[0012] Preferably, the mounting assembly includes a connecting bracket and a second telescopic rod. The connecting bracket is fixedly installed on one side of the sliding bracket, and the second telescopic rod is fixedly installed inside the frame. The output end of the second telescopic rod is fixedly connected to the connecting bracket.

[0013] Preferably, the mounting assembly includes a mounting bracket and a third telescopic rod. The mounting bracket is fixedly mounted on the upper end of the sliding bracket, the limiting block is slidably connected inside the mounting bracket, and the third telescopic rod is fixedly mounted on the upper end of the sliding bracket. The output end of the third telescopic rod is fixedly connected to the limiting block.

[0014] The beneficial effects of this utility model are: Before bending, the tapered plug is moved by pulling the lever and the spring is compressed, inserting the tapered plug into the inside of the pipe fitting. After releasing the lever, the spring applies pressure to the tapered plug, keeping it stable inside the pipe fitting. The tapered plug can adapt to the inner diameter of pipe fittings of different specifications. The other end of the pipe fitting passes through the protective bracket through the notch, thus limiting and fixing both ends of the pipe fitting. Then, the bending component is driven by the drive assembly to perform the bending operation on the pipe fitting. Because one end of the pipe fitting is positioned and fixed inside by the tapered plug, and the other end is located inside the notch of the protective bracket, it can effectively prevent the pipe fitting from accidentally springing up during the bending process, causing injury to the operator and causing a safety accident.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1 and Figure 4This utility model provides an embodiment: an electric vehicle frame bending device with a protective structure, including a frame 1, a rotating shaft 2, a bending assembly, a drive assembly, a mounting assembly, and a limiting block 6.

A pull rod 602 is slidably connected inside the mounting plate 601. A spring 603 is fixedly installed between the pull rod 602 and the mounting plate 601. One end of the pull rod 602 is fixedly installed with... The device includes a tapered plug 604. A rotating shaft 2 supports and installs the bending assembly, and an installation assembly supports and installs the limiting block 6. A drive assembly drives the rotating shaft 2 to rotate, thereby rotating the bending assembly. This, in conjunction with the limiting block 6, bends the tubing of the electric vehicle frame. An installation plate 601 installs the pull rod 602. Before bending, pulling the pull rod 602 compresses the spring 603, allowing the tapered plug 604 to be inserted into the bent tubing. The tapered plug 604 adapts to the inner diameter of tubing of different specifications. The other end of the tubing passes through the protective bracket 201 via a notch 202, thus limiting and fixing both ends of the tubing to prevent accidental springing during bending and potential safety hazards.

[0018] Please see Figure 2 and Figure 3In this embodiment, the bending assembly includes a rotating bracket 301, a support plate 302, and a first telescopic rod 303. The rotating bracket 301 is fixedly installed on the periphery of the rotating shaft 2, the support plate 302 is slidably connected to the upper end of the rotating bracket 301, and the first telescopic rod 303 is hinged inside the rotating bracket 301, with its output end hinged to the support plate 302. The bending assembly includes a first clamping block 304 and a second clamping block 305. The first clamping block 304 is fixedly installed on the upper end of the support plate 302, and the second clamping block 305 is fixedly installed on the periphery of the rotating shaft 2, with the first clamping block 304 and the second clamping block 305 corresponding to each other. By setting the rotating bracket 301, the support plate 302 is bent... The support and installation are achieved by setting a support plate 302 to support and install the first clamping block 304. The first telescopic rod 303 can drive the support plate 302 to slide on the upper end of the rotating bracket 301, thereby driving the first clamping block 304 to move and cooperate with the second clamping block 305 to clamp the pipe. The driving assembly includes a motor 401 and a reduction gearbox 402. The motor 401 is fixedly installed inside the frame 1, and the reduction gearbox 402 is set on one side of the motor 401. The input end of the reduction gearbox 402 is fixedly connected to the output end of the motor 401, and the output end of the reduction gearbox 402 is fixedly connected to the rotating shaft 2. By setting the motor 401 and the reduction gearbox 402 together, the rotating shaft 2 can be stably driven to rotate.

[0019] Please see Figure 1 and Figure 2 In this embodiment, the mounting assembly includes a sliding bracket 501 and a guide rail 502. The guide rail 502 is fixedly mounted on the upper end of the frame 1, and the sliding bracket 501 is slidably connected to the frame 1 via the guide rail 502. The mounting assembly also includes a connecting bracket 503 and a second telescopic rod 504. The connecting bracket 503 is fixedly mounted on one side of the sliding bracket 501, and the second telescopic rod 504 is fixedly mounted inside the frame 1. The output end of the second telescopic rod 504 is fixedly connected to the connecting bracket 503. Finally, the mounting assembly includes a mounting bracket 505 and a third telescopic rod 506. 505 is fixedly installed on the upper end of the sliding bracket 501, the limiting block 6 is slidably connected to the inside of the mounting bracket 505, and the third telescopic rod 506 is fixedly installed on the upper end of the sliding bracket 501. The output end of the third telescopic rod 506 is fixedly connected to the limiting block 6. By setting the second telescopic rod 504, the sliding bracket 501 can be driven to slide along the guide rail 502 on the upper end of the frame 1 through the connecting bracket. By setting the third telescopic rod 506, the limiting block 6 can be driven to slide inside the mounting bracket 505, thereby adjusting the position of the limiting block 6 to cooperate with the bending operation.

[0020] When working, first use the pull rod 602 to pull the tapered plug 604 to move and compress the spring 603, and then insert the tapered plug 604 into the inside of the bent pipe fitting. The tapered plug 604 can adapt to the inner diameter of pipe fittings of different specifications, and the other end of the pipe fitting passes through the notch 202 through the protective bracket 201, so that the two ends of the pipe fitting can be limited and fixed. The second telescopic rod 504, via a connecting support, drives the sliding bracket 501 to slide along the guide rail 502 at the upper end of the frame 1, so that the pipe fitting defined by the limiting block 6 corresponds to the first clamping block 304. Then, the first telescopic rod 303 drives the support plate 302 to slide at the upper end of the rotating bracket 301, thereby causing the first clamping block 304 to move and cooperate with the second clamping block 305 to clamp the pipe fitting. Then, the motor 401, in conjunction with the gearbox 402, stably drives the rotating shaft 2 to rotate. At this time, the rotating bracket 301 rotates with the rotating shaft 2, and under the cooperation of the first clamping block 304 and the second clamping block 305, the pipe is bent. Since one end of the pipe fitting is positioned and fixed by the tapered plug 604 inserted inside, and the other end is located inside the notch 202 of the protective bracket 201, it can effectively prevent the pipe fitting from accidentally springing up during bending, causing injury to the operator and causing a safety accident.

[0021] Through the above steps, by pulling the lever 602 to compress the spring 603 before the bending operation, the tapered plug 604 can be inserted into the inside of the bending fitting. The tapered plug 604 can adapt to the inner diameter of different specifications of fittings, and the spring 603 applies pressure to the tapered plug 604 to ensure its stability. The other end of the fitting passes through the notch 202 through the protective bracket 201, thereby limiting and fixing both ends of the fitting to prevent the fitting from accidentally springing up during the bending process and causing a safety accident. This solves the problem that current electric vehicle frame bending devices lack an effective protective structure during the bending process, which can easily lead to the fitting popping out and causing a safety accident, posing a certain safety hazard.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
