Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tooling for a buffer function in a range extender. Background Technology

[0002] Range extenders are commonly used in new energy vehicles, low-speed electric vehicles, and RVs. Their core components include an engine, generator, controller, and fuel tank. The engine drives the generator to produce electricity, which powers the equipment or is stored in the battery. The controller adjusts the power generation efficiency, and the fuel tank provides fuel for the engine. Overall, they solve the problem of short driving range for pure electric vehicles.

[0003] Existing technology patent document CN216939302U discloses a tooling for a buffer function in a range extender, belonging to the field of range-extended electric vehicle technology. This tooling for a buffer function in a range extender includes a support frame, on which a movable bracket is mounted. An axial mounting bracket is provided on the top of the movable bracket. The movable bracket includes a power source arrangement block, and a guide rail is fixedly mounted on one side of the power source arrangement block. A servo motor is disposed inside the power source arrangement block. An axial movable bracket support is slidably connected to the guide rail, and a lead screw is movably connected to the inner wall of the axial movable bracket support. By driving and controlling the movement of the axial mounting bracket through the movable bracket, not only the direction of axial movement of the axial mounting bracket can be controlled, but also the distance of axial movement can be controlled, avoiding excessive axial movement of the generator stator, thereby avoiding magnetic impact between the stator and rotor in the axial direction. This makes the axial movement closed-loop controllable and improves assembly efficiency.

[0004] In the existing technology, the buffering effect of the tooling used for the range extender is limited. In the existing technology, the mechanical vibration generated during the processing of the range extender can easily cause mechanical damage to the range extender. Furthermore, it is difficult to rotate the rod to process the workpiece. During processing, the operator needs to walk around constantly, resulting in low work efficiency and easily causing quality problems in the output range extender. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling with a buffer function for range extenders, which solves the problem of mechanical damage caused by some tooling devices with buffer functions for range extenders during the installation of range extenders.

[0006] To achieve the above objectives, this utility model provides a tooling with a buffer function for a range extender, including a worktable. A tool storage mechanism is slidably connected inside the worktable. A sliding base is slidably connected to the top of the worktable. A rotating mechanism is fixedly connected to the top of the sliding base. Four corner fixing mechanisms are fixedly connected to the top of the rotating mechanism. Multiple buffer mechanisms are fixedly connected to the top of the four corner fixing mechanisms. Each buffer mechanism includes a connecting fixing plate. A rubber buffer post is fixedly connected to the top of the connecting fixing plate. A spring is sleeved on the outside of the rubber buffer post. A limit fixing plate is fixedly connected to the top of the spring. The bottom of the spring is fixedly connected to the top of the connecting fixing plate. The top of the spring is fixedly connected to the bottom of the limit fixing plate.

[0007] The four-corner fixing mechanism includes an open plate, the bottom of which is fixedly connected to the top of the rotating mechanism. A fixed connecting plate is rotatably connected to the bottom of the open plate, and multiple L-shaped connecting plates are rotatably connected to the bottom of the fixed connecting plate. A limit component is rotatably connected to the outer side of each L-shaped connecting plate. A fixing component is fixedly connected inside the limit component. Two cylinders are fixedly connected to adjacent sides of two limit components. A limit connecting post is fixedly connected to the driving end of the cylinder. The limit connecting post is fixedly connected to the bottom inside of the fixing component. A connecting block is fixedly connected to the left side of the cylinder. A limit post is fixedly connected to the bottom inside of one of the fixing components. The outside of the limit post is fixedly connected to the inside of the two connecting blocks.

[0008] The rotating mechanism includes a gear ring, the bottom of which is rotatably connected to the top of the sliding base. A power component is fixedly connected to the bottom of the gear ring, and a gear is fixedly connected to the top of the power component.

[0009] The tool storage mechanism includes a pull-out storage box, the bottom of which is slidably connected to the inside of the workbench, and a pull ring is fixedly connected to the outside of the pull-out storage box.

[0010] The power assembly includes a protective shell, the top of which is fixedly connected to the inner top side of the workbench, and a motor is fixedly connected inside the protective shell.

[0011] The fixing component includes a horizontal connecting plate, the bottom of which is slidably connected to the top of the L-shaped connecting plate. A vertical fixing plate is fixedly connected to the right side of the horizontal connecting plate, and a cushioning pad is fixedly connected to the top left side of the vertical fixing plate.

[0012] The limiting assembly includes two limiting discs, with one side of each limiting disc rotatably connected to the outside of the transverse connecting plate, and a rotating connecting column fixedly connected inside each limiting disc.

[0013] The drive end of the motor is fixedly connected to a gear, and the outside of the gear is meshed with the inside of the gear ring.

[0014] 1. This utility model provides a tooling with a buffer function for a range extender. When the motor starts, it drives the gear to rotate. The gear meshes with the gear ring, causing the entire rotating mechanism to rotate. The range extender is placed on the limiting and fixing plate. When subjected to force, the spring is compressed and the rubber buffer column is deformed. The force is transmitted to the four corner fixing mechanism through the connecting fixing plate to achieve buffering. This can effectively reduce the mechanical damage to the range extender caused by vibration during installation.

[0015] 2. The present invention provides a tooling with a buffer function for a range extender. The cylinder pushes the limiting connecting column, which causes the horizontal connecting plate of the fixing component to slide on the L-shaped connecting plate. The limiting disc of the limiting component rotates around the rotating connecting column to cooperate with the movement of the fixing component. The vertical fixing plate moves inward, and the buffer rubber pad contacts the range extender to complete the fixation, thereby quickly fixing the range extender and improving work efficiency.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a tooling fixture with a buffer function for a range extender, including a workbench 1. The workbench 1 mainly provides an installation base and working platform for the tooling. A tool storage mechanism 2 is slidably connected inside the workbench 1. The tool storage mechanism 2 is used to store relevant tools and can be pulled out for easy access. The tool storage mechanism 2 includes a pull-out storage box 21, which is used to store tools and can be pulled out of the workbench 1. The bottom of the pull-out storage box 21 is slidably connected to the inside of the workbench 1. A pull ring 22 is fixedly connected to the outside of the pull-out storage box 21, which facilitates the pulling out of the storage box 21. A sliding base 3 is slidably connected to the top of the workbench 1. The sliding base 3 can slide on the top of the workbench 1 to adjust its position. A rotating mechanism 4 is fixedly connected to the top of the sliding base 3. The rotating mechanism 4 can drive the upper structure to rotate. The rotating mechanism 4 includes a gear ring 41. The rotating mechanism 41 meshes with gear 42 to achieve rotation. The bottom of the gear ring 41 is rotatably connected to the top of the sliding base 3. The bottom of the gear ring 41 is fixedly connected to the power component 43, which provides rotational power to the rotating mechanism 4. The power component 43 includes a protective shell 431, which protects the internal motor 432. The top of the protective shell 431 is fixedly connected to the inner top side of the workbench 1. The motor 432 is fixedly connected inside the protective shell 431, which provides power for the rotation of gear 42. The top of the power component 43 is fixedly connected to gear 42, which drives the gear ring 41 to rotate under the drive of motor 432. The top of the rotating mechanism 4 is fixedly connected to a four-corner fixing mechanism 5, which is used to fix the range extender from the four corners. The top of the four-corner fixing mechanism 5 is fixedly connected to multiple buffer mechanisms 6, which buffer and dampen the range extender.

[0024] The buffer mechanism 6 includes a connecting and fixing plate 61, which connects the buffer mechanism 6 and the four corner fixing mechanisms 5. A rubber buffer post 62 is fixedly connected to the top of the connecting and fixing plate 61. The rubber buffer post 62 provides a buffering effect through its own elasticity. A spring 63 is sleeved on the outside of the rubber buffer post 62. The spring 63 provides a buffering force through its expansion and contraction deformation. A limiting fixing plate 64 is fixedly connected to the top of the spring 63. The limiting fixing plate 64 limits the top of the spring 63 and contacts the range extender. The bottom of the spring 63 is fixedly connected to the top of the connecting and fixing plate 61, and the top of the spring 63 is fixedly connected to the bottom of the limiting fixing plate 64.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the four-corner fixing mechanism 5 includes an open plate 51, which serves as the base mounting plate for the four-corner fixing mechanism 5. The bottom of the open plate 51 is fixedly connected to the top of the rotating mechanism 4. A fixed connecting plate 52 is rotatably connected to the bottom of the open plate 51. The fixed connecting plate 52 connects the open plate 51 and an L-shaped connecting plate 53. Multiple L-shaped connecting plates 53 are rotatably connected to the bottom of the fixed connecting plate 52. The L-shaped connecting plates 53 provide a mounting and sliding base for the fixing component 55. A limit component 54 is rotatably connected to the outer side of each L-shaped connecting plate 53. The limit component 54 controls the position of the fixing component 55. To limit the movement, the limiting assembly 54 includes two limiting discs 541. The limiting discs 541 rotate and are limited by a rotating connecting post 542. The adjacent sides of the two limiting discs 541 are rotatably connected to the outside of the transverse connecting plate 551. The rotating connecting post 542 is fixedly connected inside the two limiting discs 541, connecting the two limiting discs 541 and allowing them to rotate. A fixing assembly 55 is fixedly connected inside the limiting assembly 54. The fixing assembly 55 directly contacts and fixes the range extender. The fixing assembly 55 includes a transverse connecting plate 551, which is located on the L-shaped connecting plate 551. 3. The horizontal connecting plate 551 is slidably connected to the top of the L-shaped connecting plate 53. A vertical fixing plate 552 is fixedly connected to the right side of the horizontal connecting plate 551. The vertical fixing plate 552 fixes the range extender from the side. A buffer pad 553 is fixedly connected to the top left side of the vertical fixing plate 552. The buffer pad 553 provides buffer protection for the range extender when it is fixed. Two cylinders 56 are fixedly connected to the adjacent side of the two limiting components 54. The cylinders 56 provide power to push the fixing component 55 to move. The drive end of the cylinder 56 is fixedly connected to the limiting connecting post 57. The limiting connecting post 57 connects the drive end of the cylinder 56 and the fixing component 55. The limiting connecting post 57 is fixedly connected to the bottom inside of the fixing component 55. A connecting block 59 is fixedly connected to the left side of the cylinder 56. The connecting block 59 connects the cylinder 56 and the limiting post 58. A limiting post 58 is fixedly connected to the bottom inside of one of the fixing components 55. The limiting post 58 restricts the position of the connecting block 59 and the cylinder 56. The outside of the limiting post 58 is fixedly connected to the inside of the two connecting blocks 59. A gear 42 is fixedly connected to the drive end of the motor 432. The outside of the gear 42 is meshed with the inside of the gear ring 41.

[0026] Working principle: During operation, the tool storage box 21 in the tool storage mechanism 2 is first pulled out from the workbench 1 by the pull ring 22 to retrieve the tool. Then, according to the processing requirements of the range extender, the sliding base 3 on the top of the sliding workbench 1 is adjusted to adjust its position. Next, the motor 432 of the power component 43 in the rotating mechanism 4 is started. The motor 432 drives the gear 42 to rotate. The gear 42 meshes with the gear ring 41 and drives the gear ring 41 to rotate, thereby adjusting the angle of the four corner fixing mechanism 5 at the top of the rotating mechanism 4. The range extender is placed on the limiting fixing plate 64 of the buffer mechanism 6. When vibration occurs, the spring 63 and the rubber buffer column 62 achieve buffering through deformation. The connecting fixing plate 61 connects the buffer mechanism 6 and the four corner fixing mechanism 5.

[0027] Then, the cylinder 56 in the four-corner fixing mechanism 5 is activated. The cylinder 56 pushes the fixing component 55 through the limiting connecting column 57, causing the horizontal connecting plate 551 to slide on the L-shaped connecting plate 53, which in turn drives the vertical fixing plate 552 and the buffer pad 553 to move closer to the range extender. At the same time, the limiting plate 541 of the limiting component 54 rotates around the rotating connecting column 542 to cooperate in limiting. The connecting block 59 and the limiting column 58 help stabilize the cylinder 56. The fixing connecting plate 52 and the opening plate 51 provide support to fix the range extender.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
