Description

Technical Field

[0001] This invention belongs to the field of automotive component performance testing technology, specifically relating to a performance simulation test device for an engine hood lifter used in new energy vehicles. Background Technology

[0002] The hood is a cover on the front of a vehicle used to shield the engine and other mechanical components. It not only protects internal components from environmental factors but also plays a significant role in the vehicle's overall appearance design. Some vehicles have a lifter between the hood and the body, which raises the hood to a certain height. In the event of a collision between the vehicle and a pedestrian, raising the hood can help support the pedestrian, thus protecting them.

[0003] Existing technology CN223272182U discloses a performance simulation test device for an automotive hood lifter, comprising: a base with an internal cavity for accommodating components; a guide column disposed within the cavity and extending vertically; a worktable disposed within the cavity, on which a fixed base is mounted; a fixing component including two sets of clamping mechanisms symmetrically mounted on both sides of the fixed base and a drive mechanism for controlling the opening and closing of the clamping mechanisms; a counterweight movably mounted directly above the fixing component and slidably connected to the guide column; and a detection component mounted at the bottom of the counterweight, including a force sensor and a displacement sensor. When tightening the lifter, this test device only tightens one point of the lifter, failing to guarantee the stability of the tightening and thus hindering the normal testing of the lifter. Summary of the Invention

[0004] This invention provides a performance simulation test device for engine hood lifters of new energy vehicles. Its purpose is to solve the problem that existing performance simulation test devices for engine hood lifters of new energy vehicles only tighten one part of the lifter when tightening it, which cannot guarantee the stability of the lifter tightening and thus cannot guarantee the normal testing of the lifter.

[0005] This invention provides a performance simulation test device for a hood lifter for new energy vehicles, comprising a base with a cavity for accommodating components. A worktable is fixedly connected to the center of the lower end of the cavity, and a limiting plate is fixedly connected to the upper end of the worktable. Two pairs of guide columns are fixedly connected to both sides inside the cavity, and sliding sleeves are movably mounted on the guide columns. A counterweight is fixedly connected to the two pairs of sliding sleeves, and a detection component is fixedly connected to the lower end of the counterweight. A control unit is mounted on the right side of the upper end of the base, and a support platform is fixedly connected to one side of the worktable. A fastening module is mounted on the support platform to quickly and securely lock the hood lifter.

[0006] Furthermore, the fastening module includes rotating parts and fasteners;

[0007] The rotating component includes assembly table A, rotating bar, rotating column and assembly table B. One side of assembly table A is fixed to the top of the support table. Assembly table A has a pre-reserved vertically extended assembly opening. The rotating column passes through the assembly opening. The center of the rotating column is connected to the inner wall of the assembly opening through a slewing bearing. The center of the rotating bar is clamped to the left side of the rotating column. Assembly table B is assembled on the right side of the rotating column.

[0008] Electric cylinder A is fixed to one side of the top of assembly table A. The movable end of electric cylinder A is screwed to one side of the rotating bar. When the movable end of electric cylinder A moves, it can pull the rotating bar to rotate back and forth, which in turn pulls the rotating column to rotate back and forth, which in turn pulls the assembly table B to rotate back and forth.

[0009] The fastener includes a traction unit and a pair of fastening units. The pair of fastening units are fixed to the lower wall of the assembly table B with their orientations facing left and rear respectively. When the assembly table B rotates back and forth, it can pull the fastening units alternately downward. When the fastening unit is in the orientation to the left, the traction unit can pull the fastening unit to retract or open.

[0010] The fastening unit facing left includes a guide platform, assembly platform C, a pair of linkage platforms, and a pair of fastening brackets. A connecting post A is installed between the right side of assembly platform C and assembly platform B. The guide platform is vertically and movable, clamped to the connecting post A. The center of the left end of assembly platform C is connected to assembly platform B via the connecting post. Connecting posts B are installed on both sides of the left end of assembly platform C and between assembly platform B. Each of the pair of linkage platforms is screwed onto the pair of connecting posts B. A pair of arched openings are vertically reserved on both sides of the left wall of the guide platform, with the distance between the arched openings decreasing from back to front. Each of the pair of linkage platforms has an arched opening installed on its right end. The matching connectors are each snapped into a pair of arched openings on a pair of linkage platforms. A pair of fastening brackets are each fixed to the left end of a pair of linkage platforms. When the guide platform moves upward, the right ends of the pair of linkage platforms move closer to each other. With the cooperation of the connecting column B, the left ends of the pair of linkage platforms open, which in turn pulls the pair of fastening brackets open. When the guide platform moves downward, the right ends of the pair of linkage platforms move away from each other. With the cooperation of the connecting column B, the left ends of the pair of linkage platforms move closer to each other, which in turn pulls the pair of fastening brackets closer together and fastens them. The structure of the fastening unit facing backward and the fastening unit facing left is the same.

[0011] Assembly table B is L-shaped. The lower end of the rotating column is assembled at the bend of assembly table B. A pair of fastening units are fixed to the horizontal and vertical sides of assembly table B respectively. The distance between the pair of fastening units and the bend is equal.

[0012] The traction unit includes an L-shaped mounting base. The vertical end of the mounting base is fixed to the lower wall of the mounting platform A, and the horizontal side of the mounting base is located below the mounting platform C. The lower end of the horizontal side of the mounting base is fixed to an electric cylinder B. The movable end of the electric cylinder B is facing upward, and a pressure column is installed on the movable end of the electric cylinder B. The pressure column is aligned with the lower wall of the guide platform. A spiral beryllium copper wire is installed between the guide platform and the mounting platform B. When the movable end of the electric cylinder B extends upward, it can pull the pressure column to compress the guide platform upward, and the spiral beryllium copper wire is compressed and shortened. When the movable end of the electric cylinder B retracts downward and the pressure column is reset, the deformation of the spiral beryllium copper wire can pull the guide platform downward.

[0013] Furthermore, a constraint platform is installed on the upper wall of assembly table A to constrain the reciprocating rotation area of ​​the rotating bar. When the rotating bar is pressed against one of the constraint platforms, the position of a set of fastening units is to the left. When the rotating bar is pressed against another constraint platform, the position of another set of fastening units is to the left.

[0014] Furthermore, there is a pair of connecting posts A, which are separated from each other, and a pair of spiral beryllium copper wires are provided, which are arranged laterally between the pair of connecting posts A.

[0015] Furthermore, the assembly port is located at the left end of the assembly table A, and the movable end of the electric cylinder A is positioned to the left.

[0016] Furthermore, the fastening frame includes a vertical rod, with locking plates fixed to both sides of the vertical rod. The side of the locking plate away from the vertical rod has a pre-drilled locking opening, which is arched and has several rubber protrusions installed on its inner wall.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention can securely lock the lifting device by installing the fastening module, thereby ensuring the normal conduct of the lifting device test.

[0019] 2. The fastening module of the present invention is equipped with a pair of fastening units. By locking the lifting device through the pair of fastening units, a pair of lifting devices can be locked at once, thereby speeding up the detection speed.

[0020] Through the cooperation of electric cylinder, rotating column and slewing bearing, the position of a pair of fastening units can be changed. Then, through the cooperation of connecting column, guide table and a pair of linkage table, only a single traction force is needed to pull the guide table to move, so that a pair of fastening frames can be closed or opened under the linkage action. The structure is ingenious, and there is no need for each fastening frame to be equipped with a set of traction units. The operating cost is small, and it can ensure that a pair of fastening frames can move together, and it is not easy to cause locking failure.

[0021] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-8 This invention proposes a performance simulation test device for a hood lifter for new energy vehicles, comprising a base 1 with a cavity reserved on the base 1 to accommodate components. A workbench 2 is fixedly connected to the center of the lower end of the cavity, and a limiting plate 3 is fixedly connected to the upper end of the workbench 2. Two pairs of guide columns 6 are fixedly connected to both sides inside the cavity, and sliding sleeves 7 are movably mounted on the guide columns 6. A counterweight 8 is fixedly connected to the two pairs of sliding sleeves 7, and a detection component 9 is fixedly connected to the lower end of the counterweight 8. A control unit 10 is installed on the right side of the upper end of the base 1, and a support platform 4 is fixedly connected to one side of the workbench 2. A fastening module 5 is installed on the support platform 4, and the fastening module 5 is used to quickly and securely lock the lifter.

[0034] Reference Figures 2-8 The fastening module 5 includes a rotating component and a fastener.

[0035] The rotating component includes an assembly table A51, a rotating bar 52, a rotating column 53, and an assembly table B54. One side of the assembly table A51 is fixed to the top of the support table 4. The assembly table A51 has a pre-reserved vertically extending assembly opening. The rotating column 53 passes through the assembly opening. The center of the rotating column 53 is connected to the inner wall of the assembly opening via a slewing bearing. The center of the rotating bar 52 is clamped to the left side of the rotating column 53. The assembly table B54 is assembled on the right side of the rotating column 53.

[0036] An electric cylinder A55 is fixedly connected to one side of the top of the assembly table A51. The movable end of the electric cylinder A55 is screwed to one side of the rotating bar 52. When the movable end of the electric cylinder A55 moves, it can pull the rotating bar 52 to rotate back and forth, which in turn pulls the rotating column 53 to rotate back and forth, and then pulls the assembly table B54 to rotate back and forth.

[0037] The fastener includes a traction unit 57 and a pair of fastening units 56, which are fixed to the lower wall of the assembly table B54 with their orientations facing left and rear, respectively. When the assembly table B54 rotates back and forth, it can pull the fastening units 56 downward alternately. When the fastening unit 56 is in the left orientation position, the traction unit 57 can pull the fastening unit 56 to retract or open.

[0038] The left-facing fastening unit 56 includes a guide platform 58, an assembly platform C59, a pair of linkage platforms 510, and a pair of fastening brackets 511. A connecting post A512 is installed between the right side of the assembly platform C59 and the assembly platform B54, and the guide platform 58 is vertically movable and clamped to the connecting post A512. The center of the left end of the assembly platform C59 is connected to the assembly platform B54 via a connecting platform 513. Connecting posts B514 are installed on both sides of the left end of the assembly platform C59 and between the assembly platform B54, and the pair of linkage platforms 510 are each screwed onto the pair of connecting posts B514. A pair of arched openings 515 are vertically reserved on both sides of the left wall of the guide platform 58. The distance between the pair of arched openings 515 decreases from back to front. A connecting seat 516 that matches the arched opening 515 is installed on the right end of the pair of linkage platforms 510. The connecting seat 516 on the pair of linkage platforms 510 is snapped into the pair of arched openings 515. A pair of fastening brackets 511 are fixed to the left end of the pair of linkage platforms 510.

[0039] When the guide platform 58 moves upward, the right ends of the pair of linkage platforms 510 move closer together. With the cooperation of the connecting column B514, the left ends of the pair of linkage platforms 510 open, thereby pulling the pair of fastening brackets 511 open. When the guide platform 58 moves downward, the right ends of the pair of linkage platforms 510 move away from each other. With the cooperation of the connecting column B514, the left ends of the pair of linkage platforms 510 move closer together, thereby pulling the pair of fastening brackets 511 closer together and fastening them. Through the cooperation of the guide platform 58 and the pair of linkage platforms 510, only a single traction force is needed to move the guide platform 58, and the linkage achieves the closing or opening of the pair of fastening brackets 511. The structure is ingenious and the operating cost is low.

[0040] The fastening frame 511 includes a vertical rod 5111, with locking plates 5112 fixed to both sides of the vertical rod 5111. A locking opening 5113 is provided on the side of the locking plate 5112 away from the vertical rod 5111. The locking opening 5113 is arched, and several rubber protrusions 5114 are installed on the inner wall of the locking opening 5113. When fastening the jack, the two sets of vertical locking plates 5112 can fasten two points on the jack, ensuring the reliability of the jack's fastening and thus guaranteeing the stable testing of the jack.

[0041] The architecture of the rearward-oriented fastening unit 56 and the leftward-oriented fastening unit 56 is the same.

[0042] The assembly table B54 is L-shaped. The lower end of the rotating column 53 is mounted at the bend of the assembly table B54. A pair of fastening units 56 are each fixed to the horizontal and vertical sides of the assembly table B54. The distance between the pair of fastening units 56 and the bend is equal, ensuring that after the pair of fastening units 56 are moved to the required position, they can cooperate with the traction unit 57.

[0043] The traction unit 57 includes an L-shaped mounting base 517. The vertical end of the mounting base 517 is fixed to the lower wall of the mounting platform A51, and the horizontal side of the mounting base 517 is located below the mounting platform C59. The lower end of the horizontal side of the mounting base 517 is fixed to an electric cylinder B518. The movable end of the electric cylinder B518 is upward-facing, and a pressure column 519 is mounted on the movable end of the electric cylinder B518. The pressure column 519 is aligned with the lower wall of the guide platform 58, and a spiral beryllium copper wire 520 is installed between the guide platform 58 and the mounting platform B54. When the movable end of the electric cylinder B518 extends upward, it can pull the pressure column 519 to compress the guide platform 58 upward, and the spiral beryllium copper wire 520 is compressed and shortened. When the movable end of the electric cylinder B518 retracts downward and the pressure column 519 returns to its original position, the deformation of the spiral beryllium copper wire 520 can pull the guide platform 58 downward. Through the cooperation of electric cylinders A55 and B518, the position of fastening unit 56 can be quickly changed and the fastening unit 56 at the required location can be opened or closed. There is no need to assemble an electric cylinder separately for each fastening bracket 511 in the fastening unit 56, thus reducing manufacturing costs.

[0044] On the upper wall of assembly table A51, there is a constraint table 521 used to constrain the reciprocating rotation area of ​​the rotating bar 52. When the rotating bar 52 is pressed against one of the constraint tables 521, the orientation of one set of fastening units 56 is to the left. When the rotating bar 52 is pressed against another constraint table 521, the orientation of the other set of fastening units 56 is to the left. The constraint is achieved through the constraint table 521 so that a pair of fastening units 56 can be quickly switched to the required position.

[0045] A pair of connecting posts A512 are provided, and the pair of connecting posts A512 are separated from each other. A pair of spiral beryllium copper wires 520 are provided, and the pair of spiral beryllium copper wires 520 are arranged laterally between the pair of connecting posts A512. The connecting posts A512 and spiral beryllium copper wires 520 assembled in this way can avoid interfering with each other.

[0046] The assembly port is located at the left end of the assembly table A51, and the movable end of the electric cylinder A55 is set to the left. The structure is simple and easy to manufacture.

[0047] The specific implementation method is as follows: before the fastening module 5 locks the lifting device, the pair of fastening units 56 are divided into fastening unit A and fastening unit B. The moving end of the electric cylinder A55 is reset, the position of fastening unit A is to the left, the moving end of the electric cylinder B518 is extended, and fastening unit A is opened; the position of fastening unit B is to the rear, its spiral beryllium copper wire 520 is not shortened, and fastening unit B is closed.

[0048] When the lifting device is placed in the fastening unit A, the movable end of the electric cylinder B518 shortens, and the deformation of the spiral beryllium copper wire 520 at the fastening unit A compresses the guide table 58, causing the fastening unit A to close and lock the lifting device. After the fastening unit A locks one lifting device, the movable end of the electric cylinder A55 extends, compressing the rotating bar 52 to rotate, causing the position of the fastening unit B to the left. The movable end of the electric cylinder B518 extends and compresses the guide table 58, causing the fastening unit B to open. When the lifting device is placed in the fastening unit B, the movable end of the electric cylinder B518 shortens, and the deformation of the spiral beryllium copper wire 520 at the fastening unit B compresses the guide table 58, causing the fastening unit B to close and lock the lifting device.

[0049] When the lifting device is tested, one of the tightened lifting devices, the limiting plate 3 and the detection component 9 are on the same vertical line. At this time, the other untested lifting device is on the side of the counterweight 8. The detection component 9 tests the lifting device on the top of the lifting device limiting plate 3.

[0050] After the inspection is completed, the movable end of the electric cylinder B518 extends and presses the guide table 58 to move, causing the fastening unit B to open and release the lifting device. Then, the movable end of the electric cylinder B518 returns to its original position, and the fastening unit B retracts. The movable end of the electric cylinder A55 returns to its original position, presses the rotating bar 52 to rotate, and causes the fastening unit A to be positioned to the left. The movable end of the electric cylinder B518 extends and presses the guide table 58 to move, causing the fastening unit A to open and release the lifting device, and the lifting device that has been inspected can be removed.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
