Description

Technical Field

[0001] This utility model relates to the field of testing technology for rear carpets used in electric vehicles, and in particular to a complete set of inspection tools for rear carpet assemblies used in electric vehicles. Background Technology

[0002] After the rear carpet for electric vehicles is manufactured, it needs to undergo a series of tests before installation. However, existing methods for testing the strength of electric vehicle carpets involve using torsion springs to fix the carpet in place, which can easily lead to it falling off during tension testing. For example, a complete set of inspection fixtures for an electric vehicle rear carpet assembly, as described in Chinese patent application number CN202122219268.2, shows a rotating sleeve at one end of the workbench. A pressing plate is fixedly connected to one side of the rotating sleeve, and a pressure plate is fixedly connected to the other side of the rotating sleeve. Reinforcing plates are fixedly connected to both ends of the pressure plate. Two sets of first threaded holes are opened at the top of the workbench. First threaded rods are threadedly connected to the top of the first threaded holes, and the tops of the first threaded rods pass through the reinforcing plates. First rotating parts are fixedly connected to the tops of the first threaded rods.

[0003] However, when using torsion springs to secure carpets, the torsion springs may become damaged due to elasticity over time, causing the carpet to fall off the mounting plate. This necessitates periodic replacement of the torsion springs, a time-consuming and labor-intensive process that makes it inconvenient to test the carpet's strength. Utility Model Content

[0004] To address the problem mentioned in the background art that the torsion springs may experience elastic damage over time, causing the carpet to detach from the panel, thus requiring periodic replacement of the torsion springs—a time-consuming and labor-intensive process that also hinders strength testing of the carpet—this utility model provides the following technical solution:

[0005] A complete inspection tool for rear carpet assembly of electric vehicles includes a workbench, a fixing device for clamping and fixing the carpet is provided at the top of the workbench, and a strength testing device for driving the carpet to move to the right and testing the strength of the carpet is provided on the right side of the fixing device.

[0006] The fixing device includes a fixing component 1 disposed above the workbench for clamping and fixing the carpet, and a driving component disposed at the top of the workbench for driving the fixing device to clamp and fix the carpet.

[0009] Furthermore, the drive assembly includes two support plates fixedly installed on the top of the workbench. A threaded rod for rotation is provided in the support plate on the left side, and a handwheel for driving the threaded rod to rotate is fixedly installed at the top of the threaded rod. A round rod is provided in the support plate on the right side.

[0010] Furthermore, the fixing component one includes a fixing cylinder two fixedly installed between two support plates. A fixing cylinder one is provided above the fixing cylinder two for clamping and fixing the carpet in cooperation with the fixing cylinder two. A threaded sleeve block for threaded connection with a threaded rod is fixedly installed at the front end of the fixing cylinder one. A movable block for fitting onto a round rod is fixedly installed at the rear end of the fixing cylinder one. An auxiliary shaft is provided on the right side of the fixing cylinder two.

[0011] Furthermore, the adjustment assembly includes a threaded rod II disposed in the long slot for driving the moving assembly to move left and right, and a motor for driving the threaded rod II to rotate is fixedly installed at the right end of the threaded rod II.

[0012] Furthermore, the movable component includes a movable plate that is threadedly connected to the threaded rod, and an installation frame is fixedly mounted on the top of the movable plate.

[0013] Furthermore, the second fixing component includes a bolt threadedly connected to the mounting frame, and a fixing plate for clamping and fixing the blanket in cooperation with the mounting frame is fixedly installed at the bottom end of the bolt. Several triangular nails are fixedly installed at the bottom end of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a fixing device and a strength testing device, when it is necessary to test the strength of the carpet, the carpet can be unfolded around the second fixing cylinder and along the auxiliary axis to the right. Then, by driving the threaded rod one to rotate by handwheel, the threaded sleeve block can be moved downward along the threaded rod one, so that the first fixing cylinder is close to the second fixing cylinder and clamps and fixes the carpet. Then, the other end of the carpet is placed into the installation frame, and several triangular nails under the fixing plate are controlled by bolts to penetrate the carpet and insert into the installation frame, thus fixing the other end of the carpet. Then, by controlling the threaded rod two to rotate by motor, the installation frame can be moved to the right, and the deformation of the carpet can be observed by using the indication of two scale lines.

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0026] Please see Figures 1-5This utility model provides a complete inspection tool for rear carpet assemblies of electric vehicles.

[0027] The device includes a workbench 100, a fixing device 200 for clamping and fixing the carpet at the top of the workbench 100, and a strength detection device 300 for driving the carpet to move to the right and detecting the strength of the carpet at the right side of the fixing device 200.

[0028] The top of the workbench 100 is provided with a long groove 101 for the adjustment component 310 to rotate. The long groove 101 is located in the middle of the workbench 100. The top of the workbench 100 is provided with scale lines 102 for cooperating with the strength testing device 300 to test the strength of the carpet. There are two scale lines 102, and the two scale lines 101 are symmetrically distributed at the top of the workbench 100 to facilitate the use of the strength testing device 300 to observe the deformation of the carpet by means of the indication of the two scale lines 101.

[0029] The fixing device 200 includes a fixing component 220 disposed above the workbench 100 for clamping and fixing the carpet, and a driving component 210 disposed at the top of the workbench 100 for driving the fixing device 200 to clamp and fix the carpet.

[0030] The drive assembly 210 includes two support plates 211 fixedly installed on the top of the worktable 100. The two support plates 211 are symmetrically welded to the top of the worktable 100. A threaded rod 212 for rotation is provided in the support plate 211 on the left side. The upper and lower ends of the threaded rod 212 are connected to the support plate 211 on the left side through bearings to facilitate the rotation of the threaded rod 212. A handwheel 213 for driving the threaded rod 212 to rotate is fixedly installed at the top of the threaded rod 212. A round rod 214 is provided in the support plate 211 on the right side.

[0031] The fixing assembly 220 includes a fixing cylinder 224 fixedly installed between two support plates 211. A fixing cylinder 221 is positioned above the fixing cylinder 224 for clamping and fixing the carpet in conjunction with it. Anti-slip spikes are fixedly installed on the cylinder bodies of both the fixing cylinder 221 and the fixing cylinder 224 to facilitate clamping and fixing the carpet passing between them. A threaded sleeve 222 for threaded connection with a threaded rod 212 is fixedly installed at the front end of the fixing cylinder 221, and a threaded sleeve 222 is fixedly installed at the rear end of the fixing cylinder 221. There is a movable block 223 for mounting on the round rod 214. An auxiliary shaft 225 is provided on the right side of the fixed cylinder 224, and the front and rear ends of the auxiliary shaft 225 are connected to two support plates 211 through bearings. Thus, when it is necessary to clamp and fix one side of the carpet, the carpet can be unfolded around the fixed cylinder 224 and along the auxiliary shaft 225 to the right. Then, the threaded rod 212 is driven to rotate by the handwheel 213, which can drive the threaded sleeve block 222 to move downward along the threaded rod 212. This can control the fixed cylinder 221 to approach the fixed cylinder 224 and clamp and fix the carpet.

[0032] The strength testing device 300 includes an adjustment component 310 for rotation disposed within the workbench 100, a moving component 320 for left and right movement disposed on the rod of the adjustment component 310, and a fixing component 330 for clamping and fixing the carpet disposed within the moving component 320.

[0033] The adjusting assembly 310 includes a threaded rod 312 disposed in the long groove 101 for driving the moving assembly 320 to move left and right. The left and right ends of the threaded rod 312 are connected to the groove body of the long groove 101 through bearings to facilitate the rotation of the threaded rod 312. A motor 311 for driving the rotation of the threaded rod 312 is fixedly installed at the right end of the threaded rod 312, and the shaft end of the output shaft of the motor 311 is connected to the right end of the threaded rod 312 through a coupling.

[0034] The movable component 320 includes a movable plate 321 that is threadedly connected to the threaded rod 312. The shape and size of the movable plate 321 are the same as those of the long groove 101, so that the movable plate 321 can always move left and right along the threaded rod 312 when the threaded rod 312 rotates. An installation frame 322 is fixedly installed on the top of the movable plate 321.

[0035] The second fixing component 330 includes bolts 331 threadedly connected to the mounting frame 322. A fixing plate 332 for clamping and fixing the carpet is fixedly installed at the bottom end of the bolts 331, cooperating with the mounting frame 322. Several triangular nails 333 are fixedly installed at the bottom end of the fixing plate 332 in a linear array, facilitating the insertion of the nails 333 through the carpet and into the mounting frame 322, thus fixing the other end of the carpet. Therefore, when strength testing of the carpet is required, the carpet can be unfolded around the second fixing cylinder 224 and along the auxiliary axis 225 to the right. By driving the threaded rod 212 to rotate via the handwheel 213, the threaded sleeve 222 can be moved downwards along the threaded rod 212, thereby controlling the fixing cylinder 221 to approach the fixing cylinder 224 and clamp and fix the carpet. Then, the other end of the carpet is placed into the mounting frame 322, and the bolts 331 control several triangular nails 333 under the fixing plate 322 to penetrate the carpet and insert into the mounting frame 322, thereby fixing the other end of the carpet. Then, by controlling the threaded rod 312 to rotate via the motor 311, the mounting frame 322 can be moved to the right, and the deformation of the carpet can be observed with the help of the two scale lines 101.

[0036] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
